Engine Mechanical ComponentsMany of the engine mechanical components are for marine applications. Unlike automotive engines, marine engines aresubjected to extended periods of heavy load and operation at wide‑open throttle and therefore require heavy‑duty components.Marine engine parts must also be able to resist the corrosive action of saltwater or brackish water, each of which will rust orcorrode standard automotive parts within a short period of time. We have manufactured special marine engine parts that meetspecifications required for long life and dependable performance.Failure to use recommended Quicksilver service replacement parts can result in poor engine performance or durability, rapidcorrosion of parts subjected to saltwater, and possibly complete failure of the engine.

Bravo Sterndrive Serial Number and IdentificationThe Bravo sterndrive serial number, gear ratio, model number, and bar code are embedded in the ground plate on the port sideof the sterndrive.

Sterndrive 10‑Hour Break‑In Period (New or With Replacement Gears)It is important that the following procedure be used on new sterndrive units. This break‑in procedure allows the proper seatingof drive unit gears and related components, which greatly reduces the likelihood of problems.• Avoid full throttle starts.• Do not operate at any one constant speed for extended periods of time.• Do not exceed 75% of full throttle during the first five hours. During the next five hours, operate at intermittent full throttle.• Sterndrive should be shifted into forward gear a minimum of 10 times during break‑in, with run‑in time at moderate RPM

after each shift.

Features and ControlsAudio Warning System

Your Mercury Marine power package is equipped with an audio warning system. The audio warning system monitors criticalcomponents and informs the operator when a malfunction has occurred. The warning system is not capable of protecting thepower package from damage caused by a malfunction.When an electronic control system detects a recordable malfunction the audio warning system will sound to alert the operator.The duration and type of horn sound will be dependent upon the nature of the fault condition. In the case of any horn sounding,the user should refer to the helm displays to understand the specific situation.For the operator to view the fault code of the malfunction indicated and any recommended actions, the power package must beequipped with a gauge package that supports the warning system and can display fault codes.The following instruments have screens that display fault codes:

• VesselView• SmartCraft System Tachometer• SmartCraft System Speedometer

NOTICEThe sound from an audio warning horn indicates that a critical fault malfunction has occurred. Operating a power packagewith a critical fault can damage components. If the audio warning horn emits a sound, do not continue operations unlessavoiding a hazardous situation.

If the audio warning sounds, stop the engine immediately if you are not in a hazardous situation. Investigate the cause andcorrect it, if possible. If you cannot determine the cause, consult your Mercury Diesel authorized repair facility.

InstrumentationVesselView

Your power package may be connected to a SmartCraft VesselView display. The interactive VesselView display continuouslyreports real‑time information about speed, performance, engine fault codes, fuel status, water temperature and depth, andother operating data. When VesselView detects a problem with any connected system, it displays an alarm message to theboat operator.

27198

VesselView

VesselView may also be connected to other vessel systems such as GPS, generators, and cabin environmental controls. Thisvessel integration allows the operator to monitor and control a wide range of vessel systems from a single display.Refer to your VesselView operations manual for detailed instructions on how to operate this display.

SmartCraft Speedometer and Tachometer Digital GaugesThe SmartCraft instrument package, if equipped, augments the information provided by VesselView. The instrument packagemay display:• Engine RPM• Boat speed• Coolant temperature• Oil pressure• Battery voltage• Fuel consumption• Engine operating hours

Emergency Stop SwitchAn emergency stop (E‑stop) switch is used to turn off the engines in an emergency situation, such as a person overboard or atangled propeller. When activated, an E‑stop switch interrupts the power supply to the engine and transmission. If the boat isequipped with an E‑stop switch, the E‑stop switch turns off all of the engines.

35308

Typical E-stop switch

Activation of an E‑stop switch stops the engine, or engines, immediately, but the boat can continue to coast for some distancedepending upon the velocity and degree of any turn at shutdown. While the boat is coasting, it can cause injury to anyone in theboat's path as seriously as the boat would when under power.We recommend instructing other occupants on proper starting and operating procedures should they need to operate theengine in an emergency.Accidental or unintended activation of the switch during normal operation is also possible, which can cause any or all of thefollowing potentially hazardous situations:• Occupants can be thrown forward due to unexpected loss of forward motion, and passengers in the front of the boat could

be ejected over the bow and possibly struck by the propulsion or steering components.• The operator can lose power and directional control in heavy seas, strong current, or high winds.• The operator can lose control of the vessel when docking.

Restarting an engine using the key switch or start button after an E‑stop shutdown without first turning the key switch to the offposition for at least 30 seconds will restart the engine but cause fault codes to be set. Unless you are in a potentially hazardoussituation, turn the key switch off and wait at least 30 seconds before restarting the engine or engines. If after restarting, somefault codes are still being displayed, contact your authorized Mercury Diesel repair facility.

Lanyard Stop SwitchThe purpose of a lanyard stop switch is to turn off the engine when the operator moves outside the operator's position (as inaccidental ejection from the operator's position).

a - Stop switchb - Lanyardc - Clips to the operator

Accidental ejections, such as falling overboard, are more likely to occur in:• low‑sided sport boats• bass boats• high performance boats

Accidental ejections can also occur from:• poor operating practices• sitting on the seat or gunwale at planing speeds• standing at planing speeds• operating at planing speeds in shallow or obstacle infested waters

The lanyard is a cord usually between 122 and 152 cm (4 and 5 ft) in length when stretched out, with an element on one endmade to be inserted into the switch and a snap on the other end for attaching to the operator. The lanyard is coiled to make itsat‑rest condition as short as possible to minimize the likelihood of lanyard entanglement with nearby objects. Its stretched‑outlength is made to minimize the likelihood of accidental activation should the operator choose to move around in an area closeto the normal operator's position. If it is desired to have a shorter lanyard, wrap the lanyard around the operator's wrist or leg, ortie a knot in the lanyard.Activation of the lanyard stop switch will stop the engine immediately, but the boat will continue to coast for some distancedepending upon the velocity and degree of any turn at shut down. However, the boat will not complete a full circle. While theboat is coasting, it can cause injury to anyone in the boat's path as seriously as the boat would when under power.We strongly recommend that other occupants be instructed on proper starting and operating procedures should they berequired to operate the engine in an emergency (e.g. if the operator is accidentally ejected).

! WARNINGIf the operator falls out of the boat, stop the engine immediately to reduce the possibility of serious injury or death from beingstruck by the boat. Always properly connect the operator to the stop switch using a lanyard.

Accidental or unintended activation of the switch during normal operation is also a possibility. This could cause any, or all, ofthe following potentially hazardous situations:• Occupants could be thrown forward due to unexpected loss of forward motion, a particular concern for passengers in the

front of the boat who could be ejected over the bow and possibly struck by the propulsion or steering components.• Loss of power and directional control in heavy seas, strong current or high winds.• Loss of control when docking.

! WARNINGAvoid serious injury or death from deceleration forces resulting from accidental or unintended stop switch activation. The boatoperator should never leave the operator's station without first disconnecting the stop switch lanyard from the operator.

Electronic Helm SteeringThe electronic helm steering operates using electrical signals. A computer‑controlled electric motor attached to the steeringwheel simulates the resistance feedback found in hydraulic steering systems.We recommend that you drive carefully (in an open area clear of obstructions or other boat traffic) until you are familiar with thesystem's handling characteristics and the boat's response. The electronic steering may provide a faster steering response thanexpected.To confirm your steering range from lock to lock, ensure that the starboard engine key switch is on. The engines do not have tobe running. Turn the wheel to starboard until the wheel stops at the starboard lock or end‑stop. The end‑stop is electronicallyset by the electric motor attached to the steering wheel. Begin turning the wheel to port and count the number of revolutionsuntil the wheel stops at the port lock. The number of wheel revolutions you counted moves the drives from the maximumstarboard angle to maximum port angle, with the center (straight‑ahead position) being 0°. The maximum steering angles arecontrolled within the vessel personality developed by the drive manufacturer and the boat OEM.In certain situations the electronic end‑stops of the wheel are not felt. The absence of noticeable end‑stops does not affect thesteering. The drives will still stop when they reach the full turn position at each lock. The absence of end‑stops can be the resultof the starboard key switch in the off position, a low starboard battery voltage, or a steering wheel motor fault.Your vessel's personality, as developed by the vessel manufacturer in partnership with the drive manufacturer, determines thenumber of turns lock to lock. Typically, this is approximately 2‑3/4 revolutions of the wheel. The OEM may request different lockto lock settings for other boat models.

Joystick—Basic OperationThe joystick offers intuitive control of your boat during low speed and docking maneuvers. Engine speed is limited from idle toapproximately 1700‑2500 RPM in this mode, depending on vessel and propulsion application, to prevent excessive prop washor unacceptable boat dynamics during maneuvers. DOCK mode reduces this upper range to approximately 1000‑1200 RPMand will be discussed more in the DOCK mode section. This RPM range is mainly due to engine horsepower. The levers mustbe used for vessel maneuvering if environmental conditions require more thrust than the range listed above.

Though joystick operation is easy and intuitive, you should avoid using it until you have the opportunity to become familiar withthe vessel's handling characteristics while operating the vessel with the joystick in open water. Thereafter, you shouldoccasionally practice operating without the joystick in case the joystick becomes inoperable.Both engines must be running and both ERC levers must be in neutral for the joystick to operate.

Axius Premier (If Equipped)The Axius Premier system is a fully‑integrated operation and navigation system. No aftermarket autopilot is necessary.Axius Premier utilizes the following:• CAN based navigational information from a GPS unit• An approved NMEA0183 equipped chartplotter• CAN based navigational information from an inertial measurement unit (IMU)• CAN based Precision Pilot trackpad• VesselView

! WARNINGAvoid serious injury from collision with other boats, running aground, or striking objects in the water. Always maintain adiligent lookout while the boat is operating in any Precision Pilot mode. The Precision Pilot system cannot react to avoid otherboats, shallow water, or objects in the water.

The Axius Premier Precision Pilot trackpad gives the operator control over the following modes:• Skyhook—allows the boat to hold a position without lines or anchor

NOTE: The Skyhook feature is available pending boat manufacturer personality configuration. Some boat manufacturersdo not enable Skyhook from the factory. Other boats have external notification devices (installed and manufactured by theboat builder) indicating the vessel is in Skyhook.

• Auto Heading—steers the boat on a fixed compass heading• Track Waypoint—automatically pilots the boat on a predetermined route from the chart plotter or GPS unit. This can be a

single waypoint, or a series of waypoints assembled into a route. If following a route, at each waypoint transition, thesystem will sound an alarm, which must be acknowledged before the boat will proceed to the next waypoint.

• Waypoint Sequence—similar to Track Waypoint, except the system will sound an alarm upon arriving at a waypoint andtransition automatically to the next waypoint on the route.

Function Description

Skyhook

Engages and disengages Skyhook. Mode is only available when the joystick is centered, both engines arerunning, G.P.S. and heading sensors are available, the boat is stationary, and levers are in neutral. Skyhookcan become active while drifting. The Skyhook light will flash until the boat slows itself down, then becomesolid when Skyhook is set. For example, if you are drifting forward and press Skyhook, the drives will go toreverse to slow the vessel. You may still drift forward. When the boat slows its self down, it will enableSkyhook. Skyhook will not activate if the boat is underway.

Turn < and > Each press of the button causes a 10 degree course change in auto heading. Holding the joystick port orstarboard (until the beep) initiates a one degree change in course. It affects no other autopilot features.

WaypointSequence

Engages Waypoint Sequence, driving the boat on a course set with multiple waypoints on the chart plotter.The waypoints must be on a route. See the chart plotter owners manual. Waypoint Sequence is availablewhen the "WAYPOINT SEQUENCE" button is pressed, and data (a NMEA‑0183 stream) is available from achart plotter, and the GPS and heading sensor signals are available. Waypoint sequence will follow a routeautomatically, announcing arrival at each waypoint and then turning towards the next waypoint. TrackWaypoint must be enabled first then select Waypoint Sequence.

TrackWaypoint

Route Tracking is available when data (NMEA0183 stream) is available from a chart plotter, GPS, andheading sensor signals are available. The boat will attempt to steer to a waypoint or a route from the chartplotter. Arrival at the waypoint must be acknowledged before the vessel will proceed to the next waypointalong the route.

AutoHeading

Engages Auto Heading mode, which will hold the boat on a fixed course at the speed that the operatorchooses. Heading control is available when the "Auto Heading" button is pressed, GPS and IMU signals areavailable. (See "Turn < and >" for course adjustment information.) A chart plotter not needed for this feature.

Resume Resumes previous Auto Heading course if the boat's direction has not been changed 90° or more.

NOTE: Moving the steering wheel will always take control of the boat. A slight detent will have to be overcome to give theoperator feedback that they are taking control from the Precision Pilot. Changing gears using the electronic remote control(ERC) lever will also disable the autopilot mode.

SeaCore Equipped DrivesSeaCore Components and Castings

Mercury MerCruiser SeaCore power packages are equipped with additional stainless steel components and particularaluminum castings with special coatings. Do not replace SeaCore components with non‑SeaCore. Use only the specifiedMercury MerCruiser SeaCore components and castings on these power packages.

Stainless Steel FastenersSeaCore models are equipped with additional stainless steel fasteners to maximize corrosion resistance in saltwaterenvironments.Stainless steel fasteners are subject to galling when installed without lubrication. Galling can result in fastener destruction,improper clamp loads, or both. Galled fasteners may appear to torque properly, but still have incorrect clamp loads.Apply a lubricant, such as Special Lubricant 101 or an equivalent, on the threads of stainless steel fasteners during installationto avoid galling. Lubricate at least the first 8 mm (1/4 in.) of the threads before installation.

Safe Boating SuggestionsIn order to safely enjoy the waterways, familiarize yourself with local and all other governmental boating regulations andrestrictions, and also consider the following suggestions.Mercury Marine strongly recommends that all powerboat operators complete a boating safety course. Courses are offered inthe U.S.A. by the U.S. Coast Guard Auxiliary, the Power Squadron, the Red Cross, and your state or provincial boating lawenforcement agency. Inquiries may be made to the Boating Safety Resource Center (www.uscgboating.org/) or the Boat U.S.Foundation (www.boatus.com/courseline/).• Know and obey all nautical rules and laws of the waterways.• Perform safety checks and required maintenance. Follow a regular schedule and ensure that all repairs are properly

made.• Check safety equipment on board. Here are some suggestions of the types of safety equipment to carry when boating:

Approved fire extinguishers

Paddle or oar

Signal devices: flashlight, rockets or flares, flag, and whistle or horn

Transistor radio

Tools necessary for minor repairs

First aid kit and instructions

Anchor and extra anchor line

Waterproof storage containers

Manual bilge pump and extra drain plugs

Spare operating equipment, batteries, bulbs, and fuses

Drinking water

Compass and map or chart of the area

• Watch for signs of weather change and avoid foul weather and rough‑sea boating.• Tell someone where you are going and when you expect to return.• Passenger boarding. Stop the engine whenever passengers are boarding, unloading, or are near the back (stern) of the

boat. Shifting the drive unit into neutral is not sufficient.• Use personal flotation devices. Federal law requires that there be a U. S. Coast Guard–approved, wearable‑type life

jacket (personal flotation device), correctly sized and readily accessible for every person aboard, plus a throwable cushionor ring. We strongly advise that everyone wear a life jacket at all times while in the boat.

• Prepare other boat operators. Instruct at least one person aboard in the basics of starting and operating the engine andhandling the boat in case the driver becomes disabled or falls overboard.

• Do not overload your boat. Most boats are rated and certified for maximum load (weight) capacities. Refer to your boatcapacity plate. Know your boat’s operating and loading limitations. Know if your boat will float if full of water. When indoubt, contact your authorized Mercury Marine dealer/distributor or the boat manufacturer.

• Ensure that everyone in the boat is properly seated. Do not allow anyone to sit or ride on any part of the boat that wasnot intended for such use. This includes the backs of seats, gunwales, transom, bow, decks, raised fishing seats, and anyrotating fishing seat; anywhere that sudden unexpected acceleration, sudden stopping, unexpected loss of boat control, orsudden boat movement could cause a person to be thrown overboard or into the boat. Ensure that all passengers have aproper seat and are in it before any boat movement.

• Never be under the influence of alcohol or drugs while boating. It is the law. Alcohol or drugs impairs your judgmentand greatly reduces your ability to react quickly.

• Know your boating area and avoid hazardous locations.• Be alert. The operator of the boat is responsible by law to maintain a proper lookout by sight and hearing. The operator

must have an unobstructed view particularly to the front. No passengers, load, or fishing seats should block the operator'sview when operating the boat above idle or planing transition speed. Watch out for others, keep your eyes on the water,and be aware of your wake.

• Never drive your boat directly behind a water skier in case the skier falls. As an example, your boat traveling at40 km/h (25 mph) will overtake a fallen skier who was 61 m (200 ft) in front of you in five seconds.

• Watch fallen skiers. When using your boat for water skiing or similar activities, always keep a fallen or down skier on theoperator’s side of the boat while returning to attend to the skier. The operator should always have the down skier in sightand never back up to the skier or anyone in the water.

http://www.uscgboating.org/

http://www.boatus.com/courseline/

• Report accidents. Boat operators are required by law to file a boating accident report with their state boating lawenforcement agency when their boat is involved in certain boating accidents. A boating accident must be reported if 1)there is loss of life or probable loss of life, 2) there is personal injury requiring medical treatment beyond first aid, 3) there isdamage to boats or other property where the damage value exceeds US $500.00 or 4) there is complete loss of the boat.Seek further assistance from local law enforcement.

Be Alert to Carbon Monoxide PoisoningCarbon monoxide is present in the exhaust fumes of all internal combustion engines including the outboards, sterndrives andinboard engines that propel boats, as well as the generators that power various boat accessories. Carbon monoxide is a deadlygas that is odorless, colorless and tasteless.Early symptoms of carbon monoxide poisoning, which should not be confused with seasickness or intoxication, includeheadache, dizziness, drowsiness and nausea.

! WARNINGCarbon monoxide poisoning can lead to unconsciousness, brain damage, or death. Keep the boat well ventilated while at restor underway and avoid prolonged exposure to carbon monoxide.

Good VentilationVentilate the passenger area, open the side curtains or forward hatches to remove fumes.1. Example of desired air flow through the boat.

mc79553-1

Poor VentilationUnder certain conditions, permanently enclosed or canvas enclosed cabins or cockpits with insufficient ventilation may draw incarbon monoxide. Install one or more carbon monoxide detectors in your boat.Although the occurrence is rare, on a very calm day, swimmers and passengers in an open area of a stationary boat thatcontains or is near an operating engine may be exposed to a hazardous level of carbon monoxide.1. Examples of poor ventilation while a boat is stationary:

a - Operating the engine whenthe boat is moored in aconfined space

b - Mooring close to anotherboat with its engine operating

2. Examples of poor ventilation while a boat is moving:

a - Operating the boat with thetrim angle of the bow too high

b - Operating the boat with noforward hatches open (stationwagon effect)

Avoiding Low‑Voltage ConditionsBatteries will discharge when the vessel is not regularly operated. Low voltage may cause faults for the control modules on thevessel and may cause the steering cylinder to not function. Ensure the batteries remain fully charged at all times. Use one ofthe following devices to keep the batteries charged when the vessel is not in regular use.• Trickle charger— trickle chargers are better at maintaining batteries when the vessel is not in use. Make sure the charger

is set for your specific battery type (flooded lead acid, absorbed glass mat, etc), if equipped with settings for battery types.• Battery charger—if equipped, use a battery charger connected to shore power. Refer to the boat owner’s manual for

proper operation.

The nominal "no load" (no electrical loads present, no charging or discharging, the battery is essentially on an open circuit)battery voltage, when fully charged, should be 12.5 to 12.6 VDC. Check the voltage after starting the engines and prior toleaving the dock. Do not leave the dock if battery voltage is below 12.0 VDCIf on the water and battery voltage drops below 12.0 VDC, get the battery voltage back up above 12.0 VDC by doing thefollowing:• Turn off any unnecessary electrical loads.• If equipped and operating conditions allow, start the generator set.• If possible, raise the RPM of the engine(s).• If operating conditions allow, increase engine(s) above idle RPM(1000‑1200 RPM should be sufficient). If in gear, boat

speed and wake will increase. .• If conditions do not allow an increase in boat speed (no wake zone), then put one engine in throttle only mode (1000‑1200

RPM) and increase other engine speed to maintain boat speed.

Alarms will set if voltage drops below 10.5 VDC, and the drives will lock at 9.5 VDC. It is possible to have a drive lock at ahigher voltage if there is a very high demand for steering and the batteries cannot meet that demand. If the steering locks dueto battery voltage, the battery condition must improve to a voltage above 10.5 V and the keyswitch on the affected side turnedoff and then on to reset the device. Note that cranking the engine will cause a significant short term drop in battery voltage.

Getting StartedTraditional Maneuvering with Steering and Thrust

IMPORTANT: The Axius steering system requires fluid pressure created by a engine‑driven hydraulic pump to turn the drives.You can not steer the Axius system without the engines running.You can maneuver your Axius‑equipped vessel much like a traditional sterndrive boat. However, the Axius drive systemexpands the maneuvering capability of your vessel at both slow and planing speeds. At slow speeds, the drive system iscapable of directing the thrust through independently articulating drives to produce more responsive turning of the vessel. TheAxius drive system features counter‑rotating propellers that do not produce any propsteer when accelerating or slowing down.

To Maneuver the Boat in Forward or ReversePlace one or both engines in forward or reverse gear and steer with the steering wheel as you would any comparable boat.

To Steer the Boat in Tight Turns at Low Speeds• To turn the boat in tight turns at low speeds, turn the wheel in the direction of the turn.• To increase the turn rate of the boat after the wheel is completely turned, you may increase the power to the inside drive.

To Spin the Boat at Low Speeds• Turn the drives to straight forward.• To spin starboard (to the right), place the starboard engine in reverse and the port engine in forward.• To spin port (to the left), place the port engine in reverse and the starboard engine in forward.• To increase the rate of turn, simultaneously adjust each ERC lever for more throttle. More reverse throttle will be needed to

compensate for the forward drive.

Maneuvering After Engine or Module FailureIf an engine, helm, or steering module stops functioning during use, the remaining drive may have an electronic limit whileturning inboard. This limit is to remove the possibility of the drives making contact with each other, since the active drive isunable to determine the position of the disabled drive. The boat is still operational, but maneuverability is decreased whenturning toward the drive that is not working. The drive is still capable of turning through the full range when turning away fromthe disabled drive. Use extra caution when one drive is disabled.

Models Drive Angle Electronic Limit—Inboard Turn

NOTE: The electronic limit may vary, when set by the OEM, depending on thepropulsion personality and distance between drives.

Maneuvering with the Joystick

! WARNINGA spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers.Stop the engine immediately whenever anyone in the water is near your boat.

The joystick provides a single lever interface to maneuver the vessel. Operating the vessel with the joystick is well suited forclose quarter and docking operations in most situations. The computer control system automatically calculates the steeringangle of each drive, the throttle level, and the proper gear to push or rotate the boat in a direction corresponding to a joystickmovement or twist. For example, if you move the joystick sideways, the computer control system applies a thrust to the boat inthe sideways direction. Rotating the joystick signals the system to apply thrust forces that rotate the boat around its center. Youcan move and rotate the joystick at the same time, allowing intricate movements in tight quarters.The joystick is proportional, which means that the greater distance from the center that the joystick is moved, the more thrustthat is applied to the boat in that direction, to move the boat.To maneuver the boat using the joystick:1. Both engines must be running for the joystick to operate.2. For best control, trim both drives to the full down position. VesselView will display a reminder when the joystick is initiated.3. Move both electronic remote control (ERC) levers to the neutral position.4. Move the joystick in the direction that you want the boat to move, or twist the joystick in the direction that you want the boat

to rotate. The joystick can be moved and rotated at the same time.The following picture gives a limited example of the basic responses to inputs from the joystick, and should be used forreference only. The pictures show an approximate correlation between joystick inputs and the corresponding movement of thevessel. Exact maneuvers will require multiple joystick inputs and additional user corrections to maintain the maneuver overtime.

a - Forwardb - Starboardc - Reversed - Porte - Port yawf - Starboard yaw

The control system automatically attempts to dampen bow and stern swinging (referred to as yaw) during joystick operation. Anon‑board sensor measures the yaw rate of the boat and actively counteracts the yaw motion of the boat. Factors, such as wind,water conditions or vessel loading, may act upon the vessel beyond the systems capability to correct yaw. Manual yawcorrection may be required when commanding the boat in the fore and aft, port and starboard, or diagonal directions. To correctfor unintended yaw during any maneuver just rotate the joystick in the direction the bow is desired to rotate.The following table gives an example of the basic response to inputs from the joystick for manual yaw correction.

Helm Transfer—Standard StationsHelm Transfer

Some boats are designed to allow control of the vessel from more than one location. These locations are commonly referred toas helms or stations. Helm transfer is a term used to describe the method of transferring control from one helm (or station) toanother helm.

! WARNINGAvoid serious injury or death from loss of boat control. The boat operator should never leave the active station while engine isin gear. Helm transfer should only be attempted while both stations are manned. One‑person helm transfer should only beperformed while engine is in neutral.

The helm transfer function allows the boat operator to select which helm is in control of the vessel. Before a transfer can beinitiated the ERC levers at the active helm and at the helm intended for the transfer must be in the neutral position.NOTE: If you attempt to transfer helm control when the ERC levers are not in neutral, a beep will sound and the helm transferwill not succeed until the levers at the helms are moved to neutral and transfer is requested again.Some fault codes may appear on VesselView if other control or navigation functions are attempted after the helm transferprocedure is started. To remove the fault codes it may be necessary to cycle the key switch off and on, and then restart thehelm transfer procedure. Ensure that other control and navigation inputs are performed after helm transfer is complete to avoidsetting fault codes.

NOTICEThe ERC levers must be in neutral to perform a helm transfer. While in neutral your vessel could drift and collide with objectsnearby resulting in damage. Keep an adequate look out while performing the helm transfer.

To avoid damage, use extra care when attempting a helm transfer while the vessel is close to docks, piers, or other fixed itemsor when near other vessels.

Requesting Helm TransferNOTE: Any movement of the joystick or ERC levers after pressing the "TRANSFER" button terminates the helm transferrequest. A single beep sounds and the transfer button light turns off signaling the end of the transfer request.


90-8M0070742 eng MAY 2012 Page 35

To request the transfer of vessel control from one helm to another:1. At the helm you are requesting be made active and with the ERC levers in neutral, press the "TRANSFER" button one

Helm Transfer and Precision PilotTransferring control from an active helm to an inactive helm (from one station to another station) affects the functionality ofPrecision Pilot modes. Some of the affects are listed.• Auto Heading mode is disengaged when the ERC levers are moved to neutral for helm transfer. You must re‑engage Auto

Heading at the newly active helm.• Requesting a helm transfer causes Pilot to go to Standby mode. You will need to input information at the new helm in

control.• If engaged, Skyhook will disengage when the "TRANSFER" button is pressed the second time. You must engage Skyhook

at the the newly active helm.• The Resume feature for Auto Heading does not transfer automatically. After engaging the previous Auto Heading course at

the newly active helm, the resume feature works the same as at any active station.• In Track Waypoint mode the control of the route and display of route data on your chart plotter does not automatically

transfer to the chart plotter at the requested helm. You must turn on the chart plotter at the newly active helm, input thewaypoint or waypoint route to be tracked, and re‑engage Track Waypoint.

Helm Transfer—Auxiliary Joystick StationsAuxiliary Joystick Station Transfer

Some boats are designed to allow control of the vessel from more than one auxiliary joystick stations location. Auxiliary joystickstation transfer is a term used to describe the method of transferring control from any station to an auxiliary joystick station.The auxiliary joystick station transfer function allows the boat operator to select an auxiliary joystick to control the vessel. Whilethe auxiliary joystick station is active, fault and alarm information will only be displayed at the last active helm station.The key and E‑stop switches at all the stations continue to function.To avoid damage, use extra care when attempting an auxiliary joystick station or helm station transfer while the vessel is closeto docks, piers, or other fixed items or when near other vessels.

Requesting Transfer to an Auxiliary Joystick StationTo request the transfer of vessel control from a helm station to an auxiliary joystick station:1. At the auxiliary joystick station you are requesting be made active, press the "TRANSFER" button on the control pad one

time.

This type of transfer works like a normal transfer.You may also transfer from an auxiliary joystick station to any standard helm station as long as the helm meets all of the normaltransfer requirements.

Operating Axius Premier (If Equipped)Chartplotter Requirements

Many of the features of Axius Premier use information from the chartplotter to function. However, not every chartplotter has thequality of information needed to allow these features to work properly. The chartplotter on your boat has been selected from anapproved list created and maintained by Mercury Marine. These chartplotters use specific software to meet the stringentdemands to function with the Axius Premier system.Poor quality or inaccurate information generated by unapproved chartplotters or software can cause the features to behaveerratically, unexpectedly, or not function at all. Updating software to an unapproved version can also cause the system to notfunction correctly. See your OEM dealer or call Mercury Marine Customer Service for approved plotters, plotter settings, andcompatible software in the event your chartplotter needs service.

Features

! WARNINGAvoid serious injury from collision with other boats, running aground, or striking objects in the water. Always maintain adiligent lookout while the boat is operating in any Precision Pilot mode. The Precision Pilot system cannot react to avoid otherboats, shallow water, or objects in the water.

Axius Premier includes the following Precision Pilot features:• A trackpad to control certain Precision Pilot functions.• Course correction to the port or starboard with the press of a button.• Automatic course and heading modes.• Station keeping (Skyhook)• A VesselView screen called "AUTOPILOT" (located under the Environment chapter) to display certain Precision Pilot

Precision Pilot Modes

! WARNINGIn some Precision Pilot modes—"Auto Heading," "Track Waypoint," and "Waypoint Sequence"—the boat navigates a presetcourse. The boat does not automatically respond to hazards such as other watercraft, obstacles, swimmers, or underwaterterrain. Collision with these hazards could cause boat damage, serious injury, or death. The operator must stay at the helm,ready to evade hazards and warn others of course changes.

! CAUTIONAvoid injury from unexpected turns at high speeds. Engaging the Track Waypoint or Waypoint Sequence feature while onplane can cause the boat to turn sharply. Confirm the direction of the next waypoint before engaging these autopilot features.When underway in Waypoint Sequence mode, be prepared to take appropriate action when reaching a waypoint.

Axius Premier contains several modes that can steer your vessel to a specific compass heading, or to destinations generatedfrom a chartplotter and GPS unit. If using a device to generate course information, you must be very familiar with the operationof that chartplotter and GPS unit before attempting to use Precision Pilot to steer your vessel. Precision Pilot does not controlspeed, only direction, and it can not sense hazards to navigation. These automatic modes do not relieve the operator of theresponsibility to stay at the helm and keep a vigilant lookout for other vessels, persons in the water, or hazards to navigation.If using Precision Pilot, a chartplotter, and a GPS unit to navigate along a series of waypoints (a route), be aware that the boatwill not travel to the precise location of the waypoint before initiating a turn to the next waypoint. Your chart plotter establishes azone around the point called an arrival circle, and the Precision Pilot system will announce arrival at the waypoint when theboat enters that zone.

Skyhook Station Keeping (If Equipped)The vessel may be equipped with the Skyhook Station Keeping feature. This system utilizes global positioning system (GPS)technology and an electronic compass to automatically control shifting, throttling, and steering to maintain heading andapproximate position. This feature can be helpful when waiting for space near a fuel dock, waiting for bridges to open, or whenthe water is too deep for an anchor.Skyhook does not maintain an exact fixed position, but rather will hold the vessel in a fixed compass heading within an area.The size of this area is affected by the accuracy of the GPS satellite system, the satellite signal quality, the physical position ofthe satellites relative to the receiver, solar flares, and the proximity of the receiver on the vessel to large structures and trees.Under typical operating conditions Skyhook is capable of holding the vessel within a radius of 10 m (30 ft). However, thisdistance may sometimes increase to a radius of 30 m (100 ft). Do not engage Skyhook when the vessel is within 30 m (100 ft)of any obstacle, obstruction, dock, bridge, vessel, swimmer, etc.While in Skyhook, it is essential the captain remain at the helm prepared to take control of the vessel due to changingconditions such as:• A swimmer or another vessel approaches your vessel.• Skyhook loses the satellite signal and automatically disengages.• The size of the area in which the vessel is being held increases.

Before engaging Skyhook, the captain should brief all passengers on how Skyhook operates. Direct them to stay out of thewater, not to sit or stand where they could fall overboard, and to be alert for any sudden shifts in the vessel’s position.Occasionally the Skyhook system may apply a brief surge in power to hold a position. If passengers are not prepared for thisoccurrence they may lose their balance and fall.

! WARNINGA rotating propeller, a moving boat, or a device attached to a moving boat can cause serious injury or death to people in thewater. When Skyhook is engaged, the propellers rotate and the boat moves to maintain the position of the boat. Stop theengines immediately whenever anyone is in the water near the boat.

Skyhook will not engage unless the joystick and control levers are in neutral. When Skyhook is engaged, the propellers turn,but the rotation may not be obvious. Ensure that no one is in the water near the vessel within 30 m (100 ft) and the passengersare secure when the engines are running.When Skyhook is engaged the captain must:• Remain at the helm• Watch closely for anyone in the water near the vessel• Disengage Skyhook if anyone enters the water or approaches the vessel from the water• Watch for approaching vessels and disengage Skyhook if any vessel is on an intercept course

Skyhook system response will change with wind and current conditions. Familiarize yourself with how best to position yourvessel regarding the speed and direction of wind and current. When you place the bow into the wind, the Skyhook systemresponse is smoother. Experiment to determine what works best for your vessel in various situations.Occasionally the GPS signal may weaken or become temporarily unavailable. When this happens Skyhook will sound an alarmand automatically disengage. The drives will return to neutral and the vessel will drift with the wind and current. You must beready to take control of the helm at all times.


Page 40 90-8M0070742 eng MAY 2012

IMPORTANT: Activities in the water near the vessel while Skyhook is engaged may result in injury or death. The captain,operator, and passengers should read and observe the safety warning labels on the vessel before Skyhook is engaged.The following safety warning labels are located on the vessel for reference.

NOTE: If the labels cannot be located or are not legible, they must be replaced before engaging Skyhook. For replacementlabels, contact the manufacturer of your boat or a Mercury Diesel authorized repair facility.

Auto HeadingAuto Heading allows the boat to automatically maintain a compass heading while the boat is underway.

Engaging Auto Heading1. Place at least one running engine in forward gear.

NOTE: Auto Heading does not function with the ERC levers in neutral or reverse.2. Steer the boat to the desired compass heading.


90-8M0070742 eng MAY 2012 Page 41

3. Press the "AUTO HEADING" button to engage the Auto Heading mode. The button illuminates and a single horn beepsounds acknowledging engagement. A double horn beep sounds if Auto Heading does not engage.

Track Waypoint

! WARNINGIn some Precision Pilot modes—"Auto Heading," "Track Waypoint," and "Waypoint Sequence"—the boat navigates a presetcourse. The boat does not automatically respond to hazards such as other watercraft, obstacles, swimmers, or underwaterterrain. Collision with these hazards could cause boat damage, serious injury, or death. The operator must stay at the helm,ready to evade hazards and warn others of course changes.

Track Waypoint allows the boat to automatically navigate to a specific waypoint or sequence of waypoints, called a waypointroute. This feature is intended for use in open waters, free from obstructions above and below the waterline.Using the example in the picture called Sample route:• Waypoints are shown in numbered squares within the arrival circle (a dashed‑line circle around the numbered square).• Waypoint 4 is too close to 3 to be used in the same route. Waypoints must be far enough apart that the arrival circles do

not intersect.• A route, including waypoints 1, 2, and 3, is represented by the straight dashed‑line. The autopilot system will attempt to

navigate this route. It is the responsibility of the captain to ensure the route does not contain any hazards, and to keepwatch while underway.

When the Track Waypoint feature is activated and the boat is put in operation:• The operator must remain at the helm at all times.• Do not leave the helm unattended. The feature is not designed to allow unattended operation of the vessel.• Do not use Track Waypoint as the sole source of navigation.

IMPORTANT: Track Waypoint can only be used with chartplotters approved by Mercury Marine.Waypoint data needs to be provided to VesselView by a third party chartplotter. Refer to your chartplotter's user manual fordetails.The accuracy of the feature can be affected by environmental conditions and incorrect use. Observe the following informationwhen using the Track Waypoint and Waypoint Sequencing feature.

Waypoint data—distance settings

Contingent OperationsPort Engine–Only Operation

The force feedback feature of the steering wheel is only available when the starboard key switch is in the on position. If thestarboard key switch is off or there has been damage to the starboard electrical system, the port control system monitors thesteering wheel.If only the port side is operational, or only the port key switch is in the on position, the force feedback system will not provideend stops for the steering wheel. In this case, the drive will turn in the direction of steering wheel rotation until the mechanicallimits of the drive are reached.NOTE: If the port electrical system is damaged but the starboard system is fully functional, the steering wheel will operatenormally with complete force feedback and end stops.Note that joystick is not available in single‑engine operation. However, Axius features redundant trackpad systems, so AutoHeading mode is still available during single‑engine operation.

Axius Shift Override—Emergency ProcedureIf the VesselView display shows the error message "GEAR POS DIFF" and an engine will not start or will not shift into gear,there is a problem with the Electronic Shift Control (ESC) system. If one drive is working, you may operate on one engine anddrive.

! CAUTIONUsing the emergency procedure to manually shift the drive disengages shift control at the helm. To avoid damage or injury,drive cautiously when a gear is engaged manually. To stop the drive and its propeller, you must turn the key switch to the offposition.

You can disengage the shift actuator to manually shift the drive into neutral for starting and into forward gear position foroperation. Engine speed will be limited to 1000–1200 RPM while operating in emergency shift override.To disengage the shift actuator:1. Turn the ignition switch to the off position and engage the emergency lanyard, if equipped.

! WARNINGEngine components and fluids are hot and can cause serious injury or death. Allow the engine to cool before removing anycomponents or opening any fluid hoses.

2. Unplug the shift actuator wiring harness connector.3. Move the shift lever into the neutral position. The shift actuator is in the neutral position when the shift lever is straight up

and the shift interrupt switch is fully engaged.

NOTE: Engine speed will be limited to 1000–1200 RPM while operating in emergency shift override. The Auto Headingfeature using the Axius track pad will still function but is limited to this reduced RPM setting.IMPORTANT: The boat's stopping distance increases during manual gear engagement operation.

Transporting an Axius BoatThe drives on an Axius boat are not connected by a tie bar, and can be moved independently by gravity and the vibrations oftraveling, making it possible for the drives to contact each other.Avoid the possibility of the drives making contact during travel:1. Remove the propellers (optional on short moves).2. Put the drives in the full‑up, trailer position.3. Push each drive out towards the side of the boat, past the straight ahead position.When trimmed up and pushed outward, the drives will move away from each other if they move.

CorrosionThe Causes of Corrosion

NOTICEWashing the MerCathode assembly can damage components and lead to rapid corrosion. Do not use any cleaningequipment such as brushes or high‑pressure washers to clean the MerCathode assembly.

Whenever two or more dissimilar metals (like those found on the drive) are submerged in a conductive solution, such assaltwater, polluted water, or water with a high mineral content, a chemical reaction takes place causing electrical current to flowbetween metals. The electrical current flow causes the metal that is most chemically active, or anodic, to erode. This is knownas galvanic corrosion and, if not controlled, it will in time cause the need for replacement of power package componentsexposed to water. Refer to the Marine Corrosion Protection Guide (90‑88181301).

Corrosion ProtectionThese power packages have anodes as standard equipment to help protect them from galvanic corrosion under moderateconditions. However, we recommend that a transom‑mounted anode be used for added protection to the vessel's components.The MerCathode System and sacrificial anodes will provide corrosion protection under normal usage. However, boatsconnected to AC shore power require additional protection to prevent destructive low‑voltage galvanic currents from passingthrough the shore‑power ground wire. A Quicksilver galvanic isolator can be installed to block the passage of these currentswhile providing a path to ground for dangerous fault (shock) currents. Refer to the Diesel Parts and Accessories Guide(90‑892645008) or the Mercury Accessories Guide (90‑42000010) for part numbers.IMPORTANT: If AC shore power is not isolated from the boat ground, the MerCathode System and anodes may be unable tohandle the increased galvanic corrosion potential.

Anodes and MerCathode System LocationsIMPORTANT: Replace sacrificial anodes if eroded 50 percent or more.The anodes protect the metal components on the power package from galvanic corrosion, and erode slowly over time. Thefollowing sacrificial anodes are installed at different locations on your power package.MerCathode System—The electrode assembly replaces the anode block. The system should be tested to ensure adequateoutput. The test should be performed where boat is moored, using Quicksilver Reference Electrode and Test Meter.

Antifouling PaintIMPORTANT: Corrosion damage that results from an improper type or application of antifouling paint will not be covered by thelimited warranty.IMPORTANT: You may paint the boat hull or transom with antifouling paint if the following precautions are observed:• Do not paint anodes MerCathode System reference electrode and anode, as this will render them ineffective as galvanic

corrosion inhibitors.• Copper base paint, if not prohibited by law, can be used.


Page 68 90-8M0070742 eng MAY 2012

• If using copper based antifouling paint, avoid an electrical interconnection between the Mercury MerCruiser product, anodicblocks, or MerCathode system and the paint by allowing a minimum of 40 mm (1‑1/2 in.) unpainted area on transom of theboat around these items.

a - Painted boat transomb - Minimum 40 mm (1‑1/2 in.) unpainted area around

NOTICEWashing the MerCathode assembly can damage components and lead to rapid corrosion. Do not use any cleaningequipment such as brushes or high‑pressure washers to clean the MerCathode assembly.

Do not wash the sterndrive unit with a power washer. High pressures can damage the coating on the reference wire of theMerCathode assembly, if equipped, and increase corrosion.

a - MerCathode reference electrodeb - Do not paintc - Do not pressure wash

Boat Bottom CareTo achieve maximum performance and fuel economy, the boat bottom must be kept clean. Accumulation of marine growth orother foreign matter can greatly reduce boat speed and increase fuel consumption. To ensure best performance and efficiency,periodically clean the boat bottom in accordance with manufacturer's recommendations.In some areas, it may be advisable to paint the bottom to help prevent marine growth. Refer to the following information forspecial notes about the use of antifouling paints.

To avoid damage to the engine or drive and related components, welding onthe engine, drive, or engine and drive mounted components is not recommended.

Troubleshooting Engine Related ProblemsTroubleshooting engine related problems may require information not available in this manual. Additional engine relatedtroubleshooting information can be found in the owner's manual for the engine.

Check VesselView FirstYour VesselView display is the primary information source for the various functions of your boat. Consult the VesselViewdisplay if you suspect something is wrong. VesselView displays faults and other information that can be helpful in determiningthe current status of various systems that could be causing your concern and the solution to the problem.

Diagnosing DTS ProblemsYour Mercury Diesel authorized repair facility has the proper service tools for diagnosing problems on digital throttle and shift(DTS) systems. The electronic control module (ECM)/propulsion control module (PCM) on these engines has the ability todetect some problems with the system when they occur, and store a trouble code in the ECM/PCM's memory. This code canthen be read later by a service technician using a special diagnostic tool.

Engine Guardian SystemThe Engine Guardian System monitors the critical sensors on the engine for any early indications of problems. The system willrespond to a problem by emitting a continuous beep and/or reducing engine power in order to provide engine protection.If the Engine Guardian System has been activated, reduce throttle speed. The horn will turn off when throttle speed is within theallowable limit. Consult an authorized repair facility for assistance.
