IMPORTANT SAFETYINFORMATION

Operator Responsibility

OUTBOARD MOTOR SAFETY

It is the operator’s responsibility toprovide the necessary safeguardsto protect people and property.Know how to stop the enginequickly in case of emergency.Understand the use of all controls.

Attach the emergency stop switchlanyard securely to the operator.

Stop the engine immediately ifanyone falls overboard, and do notrun the engine while the boat isnear anyone in the water.

Always stop the engine if youmust leave the controls for anyreason.

Always wear a PFD (PersonalFlotation Device) while on theboat.

Familiarize yourself with all lawsand regulations relating to boatingand the use of outboard motors.

Be sure that anyone who operatesthe outboard motor receives properinstruction.

Be sure the outboard motor isproperly mounted on the boat.

Do not remove the engine coverwhile the engine is running.

Honda BF115D/BF135A andBF150A outboard motors aredesigned for use with boats that havea suitable manufacturer’s powerrecommendation. Other uses canresult in injury to the operator ordamage to the outboard motor andother property.

Most injuries or property damage canbe prevented if you follow allinstructions in this manual and on theoutboard motor. The most commonhazards are discussed in this chapter,along with the best way to protectyourself and others.

Carbon Monoxide HazardRefuel With Care


Gasoline is extremely flammable,and gasoline vapor can explode.Refuel outdoors, in a well-ventilated area, with the enginestopped. Never smoke neargasoline, and keep other flamesand sparks away.

Refuel carefully to avoid spillingfuel. Avoid overfilling the fueltank.

After refueling, tighten the fillercap securely. If any fuel is spilled,make sure the area is dry beforestarting the engine.

Exhaust contains poisonous carbonmonoxide, a colorless, odorless gas.Breathing carbon monoxide cancause loss of consciousness and maylead to death.

If you run the engine in an area thatis confined, or even partly enclosed,the air you breathe could contain adangerous amount of exhaust gas.

Never run your outboard inside agarage or other enclosure.

This switch is used with the enginestopped to raise the outboard motorfor mooring, trailering, ormaintenance.

The power tilt switch will operatewithout turning the ignition switchON.

The power tilt switch is located onthe engine pan. It is a rocker switchwith UP and DN (down) positionsfor changing the angle of theoutboard motor. When the boat is to be moored for a

long time, tilt the outboard motor upas far as it will go. Then move the tiltlock lever to the LOCK position, andgently lower the outboard motor untilthe lever contacts the stern bracket.

The tilt lock lever is used to supportthe outboard motor in the fully-raisedposition.

Check that nobody is under theoutboard motor before opening themanual relief valve. If the manualrelief valve is loosened (turnedcounterclockwise) when the outboardmotor is tilted up, the outboard motorwill suddenly tilt down.

The outboard motor can be tiltedmanually after opening the manualrelief valve. This allows the outboardmotor to be tilted up or down whenno battery is connected.

The trim tab compensates for‘‘torque steer,’’ which is a reaction ofthe outboard motor to propellerrotation.

If uncompensated, torque steer wouldmake the outboard motor tend to turnto one side.

The engine cover latch fastens theengine cover to the outboard motor.

The Trolling Control Switch is arocker switch with UP and DN(down) positions to adjust the trollingspeed up or down in 50 RPMincrements within the range of 650 to900 RPM.

If you press and hold the TRLcontrol switch while cruising with thethrottle closed, the mode changes totrolling mode (p. ).

TAKING CARE OFUNEXPECTED PROBLEMS

The water separator buzzer sounds arapid, repeating signal when waterhas accumulated in the waterseparator.

Water should flow from the coolingsystem indicator while the engine isrunning. This shows that water iscirculating through the coolingsystem.

If water stops flowing while theengine is running, it indicates acooling system problem, such asclogged water intakes, which willcause engine overheating.

The cooling system indicatordischarge port can also becomeplugged.

When the alert triggers, the overheatindicator comes on and the buzzersounds a steady tone as the enginespeed is reduced to 1,800 rpm. If thecondition persists for another 20seconds, the engine shuts off. Referto

A priming bulb is built into the fuelhose that connects the fuel tank to theoutboard motor.

Before starting the engine, hold thepriming bulb up in the direction ofthe arrow; then squeeze the primingbulb until it feels firm. This willensure that fuel is supplied to theengine (p. ).

The anodes are made of a sacrificialmaterial that helps to protect theoutboard motor from corrosion.

There are two anodes on the gearcase, one on the stern bracket andtwo small anodes in the waterpassages of the engine block.

The engine is equipped with a revlimiter to prevent the possibility ofmechanical damage from excessiveengine speed.

The rev limiter may be activatedduring operation, limiting enginespeed, if the outboard motor istrimmed or tilted up excessively, orwhen propeller ventilation occursduring a sharp turn.

If the rev limiter is activated, checkthe trim angle of the outboard motor.

Check to see if the correct propelleris installed.

IMPORTANT SAFETYINFORMATION

BEFORE OPERATION.

To safely realize the full potential ofthis outboard motor, you need acomplete understanding of itsoperation and a certain amount ofpractice with its controls.

Before operating the outboard motorfor the first time, please review the

on page and thechapter titled

Proper break-in operation allows themoving parts to wear in smoothly forbest performance and long servicelife. Avoid continuous operation at asteady speed.

Run the engine up to a maximum of4,000 to 5,000 rpm, which is about50% to 80% of maximum throttleopening. Operating at maximum4,000 5,000 rpm should be limitedto 50% of the 60 minutes.

For your safety, do not start or runthe engine in a confined or partlyenclosed area. Your engine’s exhaustcontains poisonous carbon monoxide,a colorless, odorless gas that cancollect rapidly. Breathing carbonmonoxide can cause loss ofconsciousness and may lead to death.

Run the engine up to a maximum of2,000 to 3,000 rpm, which is about10% to 30% of maximum throttleopening. Operating at maximum2,000 3,000 rpm should be limitedto 50% of the 45 minutes.

Run the engine at trolling speed. Usethe minimum throttle openingnecessary to operate the boat at a safetrolling speed.

Do not run the engine at full throttlefor more than 5 minutes at a time.

For boats that plane easily, bring theboat up on plane, and then reduce thethrottle opening to the recommendedrpm range.

30-second full-throttle bursts are OK,but do not operate the enginecontinuously at full throttle.

CRUISING

Engine Speed

Trim

OPERATION

Excessive trim/tilt angle duringoperation can cause propellerventilation, overheating, and waterpump damage.

For rough water conditions or largewaves, slow down to prevent thepropeller from rising out of the water.

Under normal conditions, the boatwill perform best when theantiventilation plate is level with thewater surface.

When cruising into a high wind, trimthe outboard motor down slightly tolevel the boat and improve stability.With a tail wind, trim the outboardmotor up slightly.

For best fuel economy, limit thethrottle opening to 80%. Use thethrottle friction control (p. ) tohelp you hold a steady speed.

Use the power trim/tilt switch to trimthe outboard motor for the bestperformance and stability.

You can use the power trim/tiltswitch at any time, whether the boatis underway or stopped.

Press the UP or DN (down) side ofthe switch to adjust the angle of theoutboard motor.

It is necessary to trim the angle of theoutboard motor to compensate forchanges in boat load, weightdistribution, water conditions, orpropeller selection.

The engine is equipped with a revlimiter to prevent the possibility ofmechanical damage from excessiveengine speed.

If, for example, the outboard motoris tilted excessively or propellerventilation occurs during a sharp turn,the engine may overrev, activatingthe rev limiter.If engine speed becomes unstable athigh speed due to activation of therev limiter, reduce speed and checkthe trim angle of the outboard motor.

Refer to the trim meter (p. ) for anindication of whether the outboardmotor is trimmed high or low.

TRIM TAB

The trim tab compensates for‘‘torque steer,’’ which is a reaction ofthe outboard motor to propellerrotation.

If uncompensated, torque steer wouldmake the outboard motor tend to turnto one side.

When the trim tab is correctlyadjusted, steering effort is equal ineither direction.

If steering effort is unequal, loosenthe trim tab bolt and adjust the angleof the trim tab. Retighten the trim tabbolt securely.

If less effort is required to make leftturns, move the back of the trim tableft.

Adjust the trim tab in smallincrements, and retest steering effortwith the boat evenly loaded andrunning at cruising speed.

If less effort is required to make rightturns, move the back of the trim tabright.

Engine Oil Recommendations


Use only a Honda Genuine oilf ilter or a f ilter of equivalentquality specif ied f or your model.Using the wrong f ilter, or a non-Honda f ilter which is not ofequivalent quality, may causeengine damage.

Running the outboard motorwithout suf f icient cooling waterwill damage the water pump andoverheat the engine.

Oil is a major factor affectingperformance and service life. Use4-stroke detergent oil.

Start the engine and check forleaks (be sure the water level is atleast 2 inches (5 cm) above theantiventilation plate).

OIL FILTER TIGHTENINGTORQUE:

Clean the oil filter mounting base,and coat the rubber seal of the newoil filter with clean engine oil.

If you are changing the oil filterwhile the outboard motor is out ofthe water, use commerciallyavailable ear muffs and water hoseto supply water.

Stop the engine, and check the oillevel as described on page . Ifnecessary, add oil to bring the oillevel to the upper limit mark on thedipstick.

Return the outboard motor to thevertical position, and fill thecrankcase with the specifiedamount of the recommended oil.

Screw on the new filter by handuntil it contacts the engine, thenuse a suitable tool to tighten thefilter an additional 3/4 turn.

Honda 10W-30 FC-W outboardmotor oil is recommended forgeneral use.

FC-W is a registered trademark ofthe National Marine ManufacturersAssociation.

If Honda 10W-30 FC-W oil is notavailable, Honda recommends thatyou use API service category SG, SHor SJ oil. The SAE oil viscosity andservice category are in the API labelon the oil container.

REFUELINGOptional Parts : IridiumSpark Plug


Incorrect spark plugs can causeengine damage.

RECOMMENDED SPARK PLUGS:

Installation and removal procedure ofthe Iridium spark plugs are the sameas the standard spark plugs.

These spark plugs have an iridiumcoated center electrode.Be sure to observe the followingwhen servicing iridium spark plugs.

Do not clean the spark plugs. If anelectrode is contaminated withaccumulated objects or dirt,replace the spark plug with a newone.Use only a ‘‘wire-type feelergauge’’ to check the spark pluggap if necessary. To preventdamaging the iridium coating of

the center electrode, never use a‘‘leaf-type feeler gauge.’’The gap should be 0.039 0.051inches (1.0 1.3 mm).Do not adjust the spark plug gap.If the gap is out of specification,replace the spark plug with a newone.

If you do not anticipate cyclingthrough at least one complete tank offuel within a 30 day period, werecommend adding Honda MarineFuel Stabilizer each time you refuel.

Check the fuel level and refill ifnecessary. Do not fill the fuel tankabove the UPPER LIMIT. Refer tothe boat manufacturer’s instructions.

11/03/17 11:31:02 31ZX1610_076

Gasoline is highlyflammable and explosive.

You can be burned orseriously injured whenhandling fuel.

Stop the engine and keepheat, sparks, and flameaway.Handle fuel onlyoutdoors.Wipe up spillsimmediately.

FUEL RECOMMENDATIONS

Use unleaded gasoline with a pumpoctane rating of 86 or higher.


Fuel can damage paint and plastic.Be caref ul not to spill f uel whenf illing your f uel tank. Damagecaused by spilled f uel is not coveredunder warranty.

Never refill the fuel tank inside abuilding where gasoline fumes mayreach flames or sparks. Keepgasoline away from appliance pilotlights, barbecues, electric appliances,power tools, etc.

Spilled fuel is not only a fire hazard,it causes environmental damage.Wipe up spills immediately.

Your outboard motor is certified tooperate on unleaded gasoline.Unleaded gasoline produces fewerengine and spark plug deposits andextends exhaust system life.

Never use stale or contaminatedgasoline or an oil/gasoline mixture
