QSAFETY INFORMATION

8 Before mounting or operating the out-board motor, read this entire manual.Reading it should give you an under-standing of the motor and its operation.8 Before operating the boat, read any

owner’s or operator’s manuals suppliedwith it and all labels. Be sure you under-stand each item before operating.8 Do not overpower the boat with this out-

board motor. Overpowering the boatcould result in loss of control. The ratedpower of the outboard should be equal toor less than the rated horsepower capaci-ty of the boat. If the rated horsepowercapacity of the boat is unknown, consultthe dealer or boat manufacturer.8 Do not modify the outboard. Modifications

could make the motor unfit or unsafe touse.8 Never operate after drinking alcohol or

taking drugs. About 50% of all boatingfatalities involve intoxication.8 Have an approved personal flotation

device (PFD) on board for every occu-pant. It is a good idea to wear a PFDwhenever boating. At a minimum, chil-dren and non-swimmers should alwayswear PFDs, and everyone should wearPFDs when there are potentially haz-ardous boating conditions.8 Gasoline (Petrol) is highly flammable, and

its vapors are flammable and explosive.Handle and store gasoline (Petrol) care-fully. Make sure there are no gas fumesor leaking fuel before starting the engine.

8 This product emits exhaust gases whichcontain carbon monoxide, a colorless,odorless gas which may cause braindamage or death when inhaled.Symptoms include nausea, dizziness,and drowsiness. Keep cockpit and cabinareas well ventilated. Avoid blockingexhaust outlets.8 Check throttle, shift, and steering for

proper operation before starting theengine.8 Attach the engine stop switch lanyard to a

secure place on your clothing, or yourarm or leg while operating. If you acciden-tally leave the helm, the lanyard will pullfrom the switch, stopping the engine.8 Know the marine laws and regulations

where you will be boating - and obeythem.8 Stay informed about the weather. Check

weather forecasts before boating. Avoidboating in hazardous weather.8 Tell someone where you are going: leave

a Float Plan with a responsible person.Be sure to cancel the Float Plan whenyou return.8 Use common sense and good judgment

when 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 care-ful watch for obstacles and other traffic.8 Always watch carefully for swimmers dur-

ing the engine operation.8 Stay away from swimming areas.8 When a swimmer is in the water near you

shift into neutral and shut off the engine.

FUELING INSTRUCTIONS

wGASOLINE AND ITS VAPORS ARE HIGH-LY FLAMMABLE AND EXPLOSIVE!8 Do not smoke when refueling, and

keep away from sparks, flames, orother sources of ignition.8 Stop engine before refueling.8 Refuel in a well-ventilated area. Refuel

portable fuel tanks off the boat.8 Take care not to spill gasoline. If gaso-

line spills, wipe it up immediately withdry rags.8 Do not overfill the fuel tank.8 Tighten the filler cap securely after

refueling.8 If you should swallow some gasoline

inhale a lot of gasoline vapor, or getgasoline in your eyes, get immediatemedical attention.8 If any gasoline spills onto your skin,

immediately wash with soap andwater. Change clothing if gasolinespills on it.8 Touch the fuel nozzle to the filler open-

ing or funnel to help prevent electro-static sparks.

cCUse only new clean gasoline which hasbeen stored in clean containers and isnot contaminated with water or foreignmatter.

BATTERY REQUIREMENT

cCDo not use a battery that does not meetthe specified capacity. If a battery whichdoes not meet specifications is used, theelectric system could perform poorly orbe overloaded, causing electric systemdamage.

For electric start models, choose a batterywhich meets the following specifications.EMU01857

EMU01395

PROPELLER SELECTION

The performance of your outboard motorwill be critically affected by your choice ofpropeller, as an incorrect choice couldadversely affect performance and couldalso seriously damage the motor. Enginespeed depends on the propeller size andboat load. If engine speed is too high or toolow for good engine performance, this willhave an adverse effect on the engine.

Yamaha outboard motors are fitted withpropellers chosen to perform well over arange of applications, but there may beuses where a propeller with a different pitchwould be more appropriate. For a greateroperating load, a smaller-pitch propeller ismore suitable as it enables the correctengine speed to be maintained. Conversely,a larger-pitch propeller is more suitable fora smaller operating load.

Minimum cold cranking amps (CCA/EN):430 amps at -18°C (-0.4°F)

Minimum rated capacity (20HR/IEC):70 A·h

1-9

Yamaha dealers stock a range of pro-pellers, and can advise you and install apropeller on your outboard that is best suit-ed to your application.NOTE:

At full throttle and under a maximum boatload, the engine’s rpm should be within theupper half of the full throttle operatingrange, as listed in “SPECIFICATIONS” onpage 4-1. Select a propeller which fulfillsthis requirement.If operating under conditions which allowthe engine’s rpm to rise above the maxi-mum recommended range (such as lightboat loads), reduce the throttle setting tomaintain the rpm in the proper operatingrange.

1 Propeller diameter (in inches)2 Propeller pitch (in inches)3 Type of propeller (propeller mark)

Refer to the section “CHECKING PRO-PELLER” for instructions on propellerremoval and installation.

INSTALLATION

cCIncorrect engine height or obstructionsto smooth water flow (such as thedesign or condition of the boat or acces-sories such as transom ladders/depthfinder transducers) can create airbornewater spray while the boat is cruising.Severe engine damage may result if themotor is operated continuously in thepresence 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 theexhaust housing is low enough to preventwater entry into the powerhead, when waterrises due to waves when the outboard is notrunning.

MOUNTING THE OUTBOARDMOTOR

w8 Overpowering a boat may cause

severe instability. Do not install anoutboard motor with more horsepowerthan the maximum rating on thecapacity plate of the boat. If the boatdoes not have a capacity plate, consultthe boat manufacturer.8 The information presented in this sec-

tion is intended as reference only. It isnot possible to provide completeinstructions for every possibleboat/motor combination. Propermounting depends in part on experi-ence and the specific boat/motor com-bination.

wImproper mounting of the outboardmotor could result in hazardous condi-tions such as poor handling, loss of con-trol, or fire hazards. Observe the follow-ing:8 For permanently mounted models,

your dealer or other person experi-enced in proper rigging should mountthe motor. If you are mounting themotor yourself, you should be trainedby an experienced person.8 For portable models, your dealer or

other person experienced in properoutboard motor mounting shouldshow you how to mount your motor.

Mounting HeightTo run your boat at optimum efficiency, thewater-resistance (drag) of the boat and out-board motor must be made as little as pos-sible. The mounting-height of the outboardmotor greatly affects the water-resistance. Ifthe mounting-height is too high, cavitationtends to occur, thus reducing the propul-sion; and if the propeller tips cut the air, theengine speed will rise abnormally andcause the engine to overheat. If the mount-ing-height is too low, the water-resistancewill increase and thereby reduce engineefficiency. Mount the engine so that theanti-cavitation plate is between the bottomof the boat and a level 25 mm (1 in.) belowit.

BREAKING IN (RUNNING IN)ENGINE

Your new engine requires a period of break-in (running-in) to allow mating surfaces ofmoving parts to wear-in evenly. Correctbreak-in (running-in) will help ensure properperformance and longer engine life.

cCFailure to follow the break-in (running-in)procedure may result in reduced enginelife or even severe engine damage.

Break-in (running-in) time:10 hours

Break-in (running-in) premix ratio:Refer to “GASOLINE/PETROL ANDOIL MIXING”.

EMU01538

Run the engine under load (in gear with apropeller installed) as follows.1) First 10 minutes:

Run the engine at the lowest possiblespeed. A fast idle in neutral is best.

gasoline (petrol) vapor will bereleased. Gasoline (petrol) is highlyflammable, and its vapors are flamma-ble and explosive. Refrain from smok-ing, and keep away from open flamesand sparks while loosening the airvent screw.8 This product emits exhaust gases

which contain carbon monoxide, a col-orless, odorless gas which may causebrain damage or death when inhaled.Symptoms include nausea, dizziness,and drowsiness. Keep cockpit andcabin areas well ventilated. Avoidblocking exhaust outlets.

1) If there is an air vent screw on the fueltank cap, loosen it 2 or 3 turns.

2) If there is a fuel joint on the motor, firm-ly connect the fuel line to the joint. Thenfirmly connect the other end of the fuelline to the joint on the fuel tank.

NOTE:

During engine operation place the tank hori-zontally, or fuel cannot be drawn from thefuel tank.

TRIMMING OUTBOARDMOTOR

The trim angle of the outboard motor helpsdetermine the position of the bow of theboat in the water. The correct trim angle willhelp improve performance and fuel econo-my while reducing strain on the engine. Thecorrect trim angle depends upon the combi-nation of boat, engine, and propeller.Correct trim is also affected by variablessuch as the load in the boat, sea conditions,and running speed.

wExcessive trim for the operating condi-tions (either trim up or trim down) cancause boat instability and can makesteering the boat more difficult. Thisincreases the possibility of an accident.If the boat begins to feel unstable or ishard to steer, slow down and/or readjustthe trim angle.

NOTE:

Bow UpWhen the boat is on plane, a bow-up atti-tude results in less drag, greater stabilityand efficiency. This is generally when thekeel line of the boat is up about 3 to 5degrees. When trimmed out, the boat mayhave more tendency to steer to one side orthe other. Compensate for this as you steer.The trim tab can also be adjusted to helpoffset this effect.

Too much trim-out puts the bow of the boattoo high in the water. Performance andeconomy are decreased because the hull ofthe boat is pushing the water and there ismore air drag.Excessive trim-up can cause the propellerto ventilate, which reduces performance fur-ther. When trimmed-out too much, a boatmay “porpoise” (hop in the water), whichcould throw the operator and passengersoverboard.

EMU01559

Bow DownWhen the bow of the boat is down, it is eas-ier to accelerate from a standing start ontoplane.

Too much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed.Operating with excessive trim-in at higherspeeds also makes the boat unstable.Resistance at the bow is greatly increased,heightening the danger of “bow steering”and making operation difficult and danger-ous.

TILTING UP/DOWN

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

cC8 Before tilting the motor, follow the pro-

cedures under “STOPPING ENGINE”.Never tilt the motor while the engine isrunning. Severe damage from over-heating can result.8 Do not tilt up the engine by pushing

the steering handle as this could breakthe handle.

wBe sure all people are clear of the out-board motor when adjusting the tiltangle, also be careful not to pinch anybody parts between the drive unit andengine bracket.

wLeaking fuel is a fire hazard. Disconnectthe fuel line if the engine will be tilted formore than a few minutes. Otherwise, fuelmay leak. (If the fuel connector is provid-ed on the motor.)

PROCEDURE FOR TILTING UPPower trim and tilt models

1) Disconnect the fuel line or close thefuel cock.

3) Turn the tilt support lever toward you tosupport the engine.

w8 After tilting the engine, be sure to sup-

port it with the tilt support lever.Otherwise, the engine could fall backdown suddenly if oil in the power trimand tilt unit should lose pressure.8 Never operate the engine while it is

supported by the tilt support lever.

2) Push the power trim and tilt switch “UP”until the outboard has tilted up com-pletely.

TRANSPORTING ANDSTORING OUTBOARD MOTORwLeaking fuel is a fire hazard. When trans-porting and storing the outboard motor,close the air vent screw and fuel cock toprevent fuel from leaking.

EMU00326

TRAILERING OUTBOARD MOTORThe motor should be trailered and stored inthe normal running position. If there is insuf-ficient road clearance in this position, thentrailer the motor in the tilt position using amotor support device such as a transomsaver bar.For further details, consult your Yamahadealer.

w8 Never get under the lower unit while it

is tilted, even if a motor support bar isused. Severe injury could occur if theoutboard accidentally falls.8 USE CARE when transporting fuel

tank, whether in a boat or car.8 DO NOT fill fuel container to maximum

capacity. Gasoline will expand consid-erably as it warms up and can build uppressure in the fuel container. Thiscan cause fuel leakage and a potentialfire hazard.

cCDo not use the tilt support lever/knobwhen trailering the boat. The outboardmotor could shake loose from the tiltsupport and fall. If the motor can not betrailered in the down position, use anadditional support device to secure it inthe up position.

Battery Care

wBattery electrolyte is poisonous anddangerous, causing severe burns, etc. Itcontains sulfuric acid. Avoid contactwith skin, eyes, or clothing.Antidote:EXTERNAL: Flush with water.INTERNAL: Drink large quantities ofwater or milk. Follow with milk of magne-sia, beaten egg, or vegetable oil. Callphysician immediately.EYES: Flush with water for 15 minutesand get prompt medical attention.Batteries produce explosive gases: Keepsparks, flame, cigarettes, etc. away.Ventilate when charging or using in aclosed space. Always wear eye protec-tion when working near batteries.KEEP OUT OF REACH OF CHILDREN.

Batteries vary among manufacturers.Therefore the following procedures may notalways apply. Consult your battery manu-facturer’s instructions.1) Disconnect and remove the battery

from the boat. Always disconnect theblack negative lead first to prevent therisk of shorting.

2) Clean the battery casing and terminals.Fill each cell to the upper level with dis-tilled water.

3) Store the battery on a level surface in acool, dry, well-ventilated place out ofdirect sunlight.

4) Once a month, check the specific gravi-ty of the electrolyte and recharge asrequired to prolong battery life.

CLEANING AND ADJUSTING SPARKPLUG

wWhen removing or installing a sparkplug, be careful not to damage the insu-lator. A damaged insulator could allowexternal sparks, which could lead toexplosion 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. Forexample, if the center electrode porcelain isvery white, this could indicate an intake airleak or carburetion problem in that cylinder.Do not attempt to diagnose any problemsyourself. Instead, take the outboard motorto a Yamaha dealer. You should periodical-ly remove and inspect the spark plugbecause heat and deposits will cause thespark plug to slowly break down and erode.If electrode erosion becomes excessive, orif carbon and other deposits are excessive,you should replace the spark plug withanother of the correct type.

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

Standard spark plug:Refer to “SPECIFICATIONS”, page 4-1.

Spark plug gap:Refer to “SPECIFICATIONS”, page 4-1.

ADJUSTING IDLING SPEED

w8 Do not touch or remove electrical

parts when starting or during opera-tion.8 Keep hands, hair and clothes away

from flywheel and other rotating partswhile engine is running.

cCThis procedure must be performed whilethe outboard motor is in the water. Aflushing attachment or test tank can beused.

A diagnostic tachometer should be used forthis procedure.1) Start the engine and allow it to warm up

fully in Neutral until it is runningsmoothly. If the outboard is mounted ona boat, be sure the boat is tightlymoored.

2) Adjust the throttle stop-screw 1 to setthe idling speed to specification (see“SPECIFICATIONS” on page 4-1) byturning the stop-screw clockwise toincrease the idling speed, and turning itcounterclockwise to decrease the idlingspeed.

NOTE:

Correct idling-speed adjustment is only pos-sible if the engine is fully warmed-up. If notwarmed up fully, the speed setting will tendto be too high. If you have difficulty obtain-ing the specified idle, consult a Yamahadealer or other qualified mechanic.
