Safety information

�

Before mounting or operating the outboardmotor, read this entire manual. Reading itshould give you an understanding of themotor and its operation.

�

Before operating the boat, read any own-er’s or operator’s manuals supplied with itand all labels. Be sure you understandeach item before operating.

�

Do not overpower the boat with this out-board motor. Overpowering the boat couldresult in loss of control. The rated power of

the outboard should be equal to or lessthan the rated horsepower capacity of theboat. If the rated horsepower capacity ofthe boat is unknown, consult the dealer orboat manufacturer.

�

Do not modify the outboard. Modificationscould make the motor unfit or unsafe touse.

�

Incorrect propeller selection and incorrectuse may not only cause engine damage,but also adversely affect fuel consumption.Consult your dealer for correct use.

�

Never operate after drinking alcohol or tak-ing drugs. About 50% of all boating fatali-ties involve intoxication.

�

Have an approved personal flotation de-vice (PFD) on board for every occupant. Itis a good idea to wear a PFD wheneverboating. At a minimum, children and non-swimmers should always wear PFDs, andeveryone should wear PFDs when thereare potentially hazardous boating condi-tions.

�

Gasoline is highly flammable, and its va-pors are flammable and explosive. Handleand store gasoline carefully. Make surethere are no gas fumes or leaking fuel be-fore starting the engine.

�

This product emits exhaust gases whichcontain carbon monoxide, a colorless,odorless gas which may cause brain dam-age or death when inhaled. Symptoms in-clude nausea, dizziness, and drowsiness.Keep cockpit and cabin areas well ventilat-ed. Avoid blocking exhaust outlets.

�

Check throttle, shift, and steering for prop-er operation before starting the engine.

Know the marine laws and regulationswhere you will be boating—and obeythem. For basic boating rules, see “Rulesof the road” on page 5.

�

Stay informed about the weather. Checkweather forecasts before boating. Avoidboating in hazardous weather.

�

Tell someone where you are going: leavea Float Plan with a responsible person. Besure to cancel the Float Plan when you re-turn.

�

Use common sense and good judgmentwhen boating. Know your abilities, and besure you understand how your boat han-dles under the different boating conditionsyou may encounter. Operate within yourlimits, and the limits of your boat. Alwaysoperate at safe speeds, and keep a carefulwatch for obstacles and other traffic.

�

Always watch carefully for swimmers dur-ing the engine operation.

�

Stay away from swimming areas.

�

When a swimmer is in the water near youshift into neutral and shut off the engine.

�

Do not illegally discard empty containersused to replace or replenish oil. For thecorrect processing of empty containers,consult the dealer where you purchasedthe oil.

�

When replacing oils used to lubricate theproduct (engine or gear oil), be sure towipe away any spilt oil. Never pour oil with-out using a funnel or similar device. If nec-essary, verify the necessary replacementprocedure with the dealer.

Basic boating rules (Rules of the road)

Just as there are rules which apply when youare driving on streets and high ways, thereare waterway rules which apply when youare driving your boat. These rules are usedinternationally, and are also enforced by theUnited States Coast Guard and local agen-cies. You should be aware of these rules,and follow them whenever you encounteranother vessel on the water.Several sets of rules prevail according togeographic location, but are all basically thesame as the International Rules of the Road.The rules presented here in your Owner’sManual are condensed, and have been pro-vided for your convenience only. Consultyour local U.S. Coast Guard Auxiliary or De-partment of Motor Vehicles for a completeset of rules governing the waters in whichyou will be using your boat.

EMU25510

Steering and sailing rules and sound signals

Whenever two vessels on the water meetone another, one vessel has the right-of-way; it is called the “stand-on” vessel. Thevessel which does not have the right-of-wayis called the “give-way” or “burdened” vessel.These rules determine which vessel has theright-of-way, and what each vessel shoulddo.

Stand-on vessel

The vessel with the right-of-way has the duty

ZMU01949

General information

6

to continue its course and speed, except toavoid an immediate collision. When youmaintain your direction and speed, the othervessel will be able to determine how best toavoid you.

Give-way vessel

The vessel which does not have the right-of-way has the duty to take positive and timelyaction to stay out of the way of the Stand-Onvessel. Normally, you should not cross infront of the vessel with the right-of-way. Youshould slow down or change directions brief-ly and pass behind the other vessel. Youshould always move in such a way that theoperator of the other vessel can see whatyou are doing.

“The general prudential rule”

This rule is called Rule 2 in the InternationalRules and says,“In obeying and construing these rules dueregard shall be had to all dangers of naviga-tion and collision, and to any special circum-stances, which may render a departure fromthe above rules necessary in order to avoidimmediate danger.”In other words, follow the standard rules ex-cept when a collision will occur unless bothvessels try to avoid each other. If that is thecase, both vessels become “Give-Way” ves-sels.

EMU25520

Rules when encountering vessels

There are three main situations which youmay encounter with other vessels whichcould lead to a collision unless the SteeringRules are followed:

Meeting:

(you are approaching another ves-sel head-on)

Crossing:

(you are traveling across the oth-er vessel’s path)

Overtaking:

(you are passing or beingpassed by another vessel)

In the following illustration, your boat is in thecenter. You should give the right-of-way toany vessels shown in white area (you are theGive-Way vessel). Any vessels in the shad-ed area must yield to you (they are the Give-Way vessels). Both you and the meetingvessel must alter course to avoid each other.

Meeting

If you are meeting another power vesselhead on, and are close enough to run the riskof collision, neither of you has the right-of-way! Both of you should alter course to avoidan accident. You should keep the other ves-sel on your port (left) side. This rule doesn’tapply if both of you will clear one another ifyou continue on your set course and speed.

Crossing

When two power driven vessels are crossingeach other’s path close enough to run therisk of collision, the vessel which has the oth-er on the starboard (right) side must keep out

General information

7

of the way of the other. If the other vessel ison your right, you must keep out of its way;you are the Give-Way vessel. If the othervessel is on your port (left) side, rememberthat you should maintain course and direc-tion, provided the other vessel gives you theright-of-way as it should.

Overtaking

If you are passing another vessel, you arethe “Give-Way” vessel. This means that theother vessel is expected to maintain itscourse and speed. You must stay out of itsway until you are clear of it. Likewise, if an-other vessel is passing you, you shouldmaintain your speed and direction so that theother vessel can steer itself around you.

EMU25530

Other special situations

There are three other rules you should beaware of when driving your boat around oth-er vessels.

Narrow channels and bends

When navigating in narrow channels, youshould keep to the right when it is safe andpractical to do so. If the operator of a power-driven vessel is preparing to go around abend that may obstruct the view of other wa-ter vessels, the operator should sound a pro-longed blast on the whistle (4 to 6 seconds).If another vessel is around the bend, it tooshould sound the whistle. Even if no reply is

heard, however, the vessel should still pro-ceed around the bend with caution. If younavigate such waters with your boat, you willneed to carry a portable air horn, availablefrom local marine supply stores.

Fishing vessel right-of-way

All vessels which are fishing with nets, linesor trawls are considered to be “fishing ves-sels” under the International Rules. Vesselswith trolling lines are not considered fishingvessels. Fishing vessels have the right-of-way regardless of position. Fishing vesselscannot, however, impede the passage ofother vessels in narrow channels.

Sailing vessel right-of-way

Sailing vessels should normally be given theright-of-way. The exceptions to this are:1. When the sailing vessel is overtaking

the power-driven vessel, the power-driv-en vessel has the right-of-way.

2. Sailing vessels should keep clear of anyfishing vessel.

3. In a narrow channel, a sailing vesselshould not hamper the safe passage ofa power-driven vessel which can navi-gate only in such a channel.

Reading buoys and other markers

The waters of the United states are markedfor safe navigation by the lateral system ofbuoyage. Simply put, buoys and markershave an arrangement of shapes, colors,numbers and lights to show which side of thebuoy a boater should pass on when navigat-ing in a particular direction. The markings onthese buoys are oriented from the perspec-tive of being entered from seaward (the boat-er is going towards the port). This means thatred buoys are passed on the starboard(right) side when proceeding from open wa-ter into port, and black buoys are to port (left)side. When navigating out of port, your posi-

General information

8

tion with respect to the buoys should be re-versed; red buoys should be to port andblack buoys to starboard.Many bodies of water used by boaters areentirely within the boundaries of a particularstate. The Uniform State Waterway MarkingSystem has been devised for these waters.This system uses buoys and signs with dis-tinctive shapes and colors to show regulato-ry or advisory information. These markersare white with black letters and orangeboarders. They signify speed zones, restrict-ed areas, danger areas, and general infor-mation.Remember, markings may vary by geo-graphic location. Always consult local boat-ing authorities before driving your boat inunfamiliar waters.

ter.

EMU25570

Gasoline

If knocking or pinging occurs, use a differentbrand of gasoline or premium unleaded fuel.

Gasohol

There are two types of gasohol: gasohol con-taining ethanol and that containing metha-nol. Gasohol containing ethanol can be usedif ethanol content does not exceed 10% andthe fuel meets minimum octane ratings.Yamaha does not recommended gasoholcontaining methanol because it can causefuel system damage or engine performanceproblems.

EMU25660

Engine oil

Use Yamalube 2-M outboard oil. If Ya-malube 2-M is not available, use only anoth-er outboard motor manufacturer’s factory-brand oil with TC-W3 rating.

CAUTION:

ECM01290

Serious engine damage can result fromthe use of lower quality oil, includingsome commonly available oil brands with“TC-W3” on their label. To avoid the risk,use only Yamalube 2-M or, if necessary,another outboard motor manufacturer’s

factory-brand TC-W3 oil.

Battery specifications

NOTE:

The engine cannot be started if battery volt-

age is too low.

EMU25742

Propeller selection

The performance of your outboard motor willbe critically affected by your choice of propel-ler, as an incorrect choice could adverselyaffect performance and could also seriouslydamage the motor. Engine speed dependson the propeller size and boat load. If enginespeed is too high or too low for good engineperformance, this will have an adverse effecton the engine.Yamaha outboard motors are fitted with pro-pellers chosen to perform well over a rangeof applications, but there may be uses wherea propeller with a different pitch would bemore appropriate. For a greater operatingload, a smaller-pitch propeller is more suit-able as it enables the correct engine speedto be maintained. Conversely, a larger-pitchpropeller is more suitable for a smaller oper-ating load.Yamaha dealers stock a range of propellers,and can advise you and install a propeller onyour outboard that is best suited to your ap-plication.

NOTE:

Select a propeller which will allow the engineto reach the middle or upper half of the oper-ating range at full throttle with the maximumboat load. If operating conditions such aslight boat loads then allow the engine r/min torise above the maximum recommendedrange, reduce the throttle setting to maintain

the engine in the proper operating range.

For instructions on propeller removal and in-stallation, see page 60.

EMU25770

Start-in-gear protection

Yamaha outboard motors or Yamaha-ap-proved remote control units are equippedwith start-in-gear protection device(s). Thisfeature permits the engine to be started onlywhen it is in neutral. Always select neutralbefore starting the engine.

The lock plate must be attached to the en-gine stop switch for the engine to run. Thelanyard should be attached to a secure placeon the operator’s clothing, or arm or leg.Should the operator fall overboard or leavethe helm, the lanyard will pull out the lockplate, stopping ignition to the engine. Thiswill prevent the boat from running away un-der power.

WARNING

EWM00120

�

Attach the engine stop switch lanyardto a secure place on your clothing, or

your arm or leg while operating.

�

Do not attach the lanyard to clothingthat could tear loose. Do not route thelanyard where it could become entan-gled, preventing it from functioning.

�

Avoid accidentally pulling the lanyardduring normal operation. Loss of en-gine power means the loss of moststeering control. Also, without enginepower, the boat could slow rapidly. Thiscould cause people and objects in the

boat to be thrown forward.

NOTE:

The engine cannot be started with the lock

plate removed.

Installation

CAUTION:

ECM00110

Incorrect engine height or obstructionsto smooth water flow (such as the designor condition of the boat, or accessoriessuch as transom ladders or depth findertransducers) can create airborne waterspray while the boat is cruising. Severeengine damage may result if the motor isoperated continuously in the presence of

airborne water spray.

NOTE:

During water testing check the buoyancy ofthe boat, at rest, with its maximum load.Check that the static water level on the ex-haust housing is low enough to prevent wa-ter entry into the powerhead, when waterrises due to waves when the outboard is not

running.

EMU26910

Mounting the outboard motor

WARNING

EWM00820

�

Overpowering a boat could cause se-vere instability. Do not install an out-board motor with more horsepowerthan the maximum rating on the capac-ity plate of the boat. If the boat does nothave a capacity plate, consult the boatmanufacturer.

�

The information presented in this sec-tion is intended as reference only. It isnot possible to provide complete in-structions for every possible boat andmotor combination. Proper mountingdepends in part on experience and the

specific boat and motor combination.

WARNING

EWM00830

Improper mounting of the outboard mo-tor could result in hazardous conditionssuch as poor handling, loss of control, orfire hazards. Observe the following:

�

For permanently mounted models, yourdealer or other person experienced inproper rigging should mount the motor.If you are mounting the motor yourself,you should be trained by an experi-enced person.

�

For portable models, your dealer or oth-er person experienced in proper out-board motor mounting should show

you how to mount your motor.

Mount the outboard motor on the center line(keel line) of the boat, and ensure that theboat itself is well balanced. Otherwise theboat will be hard to steer. For boats withouta keel or which are asymmetrical, consultyour dealer.

EMU26950

Mounting height

To run your boat at optimum efficiency, thewater resistance (drag) of the boat and out-board motor must be made as little as possi-ble. The mounting height of the outboard

1. Center line (keel line)

1 ZMU01873

Operation

33

motor greatly affects the water resistance. Ifthe mounting height is too high, cavitationtends to occur, thus reducing the propulsionand causing the engine to overheat. If themounting height is too low, the water resis-tance will increase and thereby reduce en-gine efficiency. Mount the outboard motor sothat the anti-cavitation plate is about 130 mm(5 in.) above the bottom of the boat.

NOTE:

�

The optimum mounting height of the out-board motor is affected by the boat andmotor combination and the desired use.Test runs at different heights can help de-termine the optimum mounting height.Consult your Yamaha dealer or boat man-ufacturer for further information on deter-mining the proper mounting height.

�

For instructions on setting the trim angle of

the outboard motor, see page 42.

Ring Free Fuel Additive

Gasoline is a precise blend of many differentsubstances, each chosen to give certaincharacteristics. Gasoline blends have beenchanging in recent years in response to con-cerns about pollution and resulting emis-sions regulations. One of the most obviouschanges has been the elimination of leadfrom most fuels.As gasoline has changed, the amount of ad-ditives such as aromatics and oxygenateshas increased. These additives are impor-tant for the engines in passenger cars, butthey can have detrimental effects in marineengines, because of increased deposits inthe combustion chamber. When enough de-posits collect, piston rings begin sticking.Performance drops and engine wear in-creases dramatically.While many additives available may reducedeposits, Yamaha recommends the use of

Trimming outboard motor

The trim angle of the outboard motor helpsdetermine the position of the bow of the boatin the water. Correct trim angle will help im-prove performance and fuel economy whilereducing strain on the engine. Correct trimangle depends upon the combination ofboat, engine, and propeller. Correct trim isalso affected by variables such as the load inthe boat, sea conditions, and running speed.

WARNING

EWM00740

Excessive trim for the operating condi-tions (either trim up or trim down) cancause boat instability and can makesteering the boat more difficult. This in-creases the possibility of an accident. Ifthe boat begins to feel unstable or is hardto steer, slow down and/or readjust the

trim angle.

WARNING

EWM00751

�

Be sure all people are clear of the out-board motor when adjusting the tilt an-gle, also be careful not to pinch anybody parts between the drive unit andclamp bracket.

�

Use caution when trying a trim positionfor the first time. Increase speed gradu-ally and watch for any signs of instabil-ity or control problems. Improper trimangle can cause loss of control.

�

If equipped with a power trim and tiltswitch located on the bottom cowling,use the switch only when the boat is ata complete stop with the engine off. Donot adjust the trim angle with this

switch while the boat is moving.

Adjust the outboard motor trim angle usingthe power trim and tilt switch.

To raise the bow (trim-out), press the switch“ ” (up).To lower the bow (trim-in), press the switch“ ” (down).Make test runs with the trim set to differentangles to find the position that works best foryour boat and operating conditions.

EMU27911

Adjusting boat trim

When the boat is on plane, a bow-up attituderesults in less drag, greater stability and effi-ciency. This is generally when the keel line ofthe boat is up about 3 to 5 degrees. With thebow up, the boat may have a greater tenden-

cy to steer to one side or the other. Compen-sate for this as you steer. The trim tab canalso be adjusted to help offset this effect.When the bow of the boat is down, it is easierto accelerate from a standing start ontoplane.

Bow Up

Too much trim-out puts the bow of the boattoo high in the water. Performance and econ-omy are decreased because the hull of theboat is pushing the water and there is moreair drag. Excessive trim-out can also causethe propeller to ventilate, which reduces per-formance further, and the boat may “por-poise” (hop in the water), which could throwthe operator and passengers overboard.

Bow Down

Too much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed. Oper-ating with excessive trim-in at higher speeds

also makes the boat unstable. Resistance atthe bow is greatly increased, heightening thedanger of “bow steering” and making opera-tion difficult and dangerous.

NOTE:

Depending on the type of boat, the outboardmotor trim angle may have little effect on the

trim of the boat when operating.

EMU27933

Tilting up and down

If the engine will be stopped for some time orif the boat is moored in shallows, the out-board motor should be tilted up to protect thepropeller and casing from damage by colli-sion with obstructions, and also to reducesalt corrosion.

Cleaning and adjusting spark plug

WARNING

EWM00560

When removing or installing a spark plug,be careful not to damage the insulator. Adamaged insulator could allow external

sparks, which could lead to explosion or

fire.

The spark plug is an important engine com-ponent and is easy to inspect. The conditionof the spark plug can indicate somethingabout the condition of the engine. For exam-

ple, if the center electrode porcelain is verywhite, this could indicate an intake air leak orcarburetion problem in that cylinder. Do notattempt to diagnose any problems yourself.Instead, take the outboard motor to aYamaha dealer. You should periodically re-move and inspect the spark plug becauseheat and deposits will cause the spark plugto slowly break down and erode. If electrodeerosion becomes excessive, or if carbon andother deposits are excessive, you should re-place the spark plug with another of the cor-rect type.

Before fitting the spark plug, measure theelectrode gap with a wire thickness gauge;adjust the gap to specification if necessary.

When fitting the plug, always clean the gas-ket surface and use a new gasket. Wipe offany dirt from the threads and screw in the

spark plug to the correct torque.

NOTE:

If a torque-wrench is not available when youare fitting a spark plug, a good estimate ofthe correct torque is 1/4 to 1/2 a turn past fin-ger-tight. Have the spark plug adjusted to thecorrect torque as soon as possible with a

torque-wrench.
