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

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.
EMU01208
START-IN-GEAR PROTECTION
Yamaha outboard motors which have thepictured label 1 affixed to them or Yamahaapproved remote control units are equippedwith start-in-gear protection device(s). Thisfeature permits the engine to be startedonly when it is Neutral. Always selectNeutral before starting the engine.

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.

STARTING ENGINE
w8 Before starting the engine, make sure
that the boat is tightly moored and thatyou can steer clear of any obstruc-tions. Be sure there are no swimmersin the water near you.8 When the air vent screw is loosened,
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.
3) Squeeze the primer bulb with the outletend up until you feel it become firm.

WARMING UP ENGINE
1) Before beginning operation, allow theengine to warm up at idling speed for 3minutes. (Failure to do this will shortenengine life.) Gradually return the chokeknob to the home position as theengine warms up.
2) Check for a steady flow of water fromthe cooling-water pilot hole.
cCA continuous flow of water from the pilothole shows that the water pump ispumping water through the cooling pas-sages. If water is not flowing out of thepilot hole at all times while the engine isrunning, do not continue to run theengine. Overheating and serious dam-age could occur. Stop the engine andcheck to see if the water inlet on thelower casing is blocked. If the problemcannot be found and corrected, consultyour Yamaha dealer.

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:
Refer to the section “ADJUSTING TRIMANGLE” for instructions on usage.

from the clamp bracket while tilting themotor up slightly.
3) Reposition the rod in the desired hole.To raise the bow (“trim-out”), move the rodaway from the transom.To lower the bow (“trim-in”), move the rodtoward the transom.Make test runs with the trim set to differentangles to find the position that works bestfor your boat and operating conditions.
w8 Stop the engine before adjusting the
trim angle.8 Use care to avoid being pinched when
removing or installing the rod.8 Use caution when trying a trim posi-
tion for the first time. Increase speedgradually and watch for any signs ofinstability or control problems.Improper trim angle can cause loss ofcontrol.
NOTE:
The outboard motor trim angle can bechanged approximately 4 degrees by shift-ing the trim adjusting-rod one hole.

Power Trim/Tilt Model
w8 Be sure all people are clear of the out-
board motor when adjusting thetrim/tilt angle, also be careful not topinch any body parts between thedrive unit and clamp bracket.8 Use caution when trying a trim posi-
tion for the first time. Increase speedgradually and watch for any signs ofinstability or control problems.8 Use the power trim/tilt switch located
on the bottom engine cowling (ifequipped) only when the boat is at acomplete stop with the engine off.
The outboard motor trim angle can beadjusted operating the power trim/tilt switch1.
To raise the bow (“trim-out”), push theswitch UP.
To lower the bow (“trim-in”), push the switchDN.
Make test runs with the trim set to differentangles to find the position that works bestfor your boat and operating conditions.NOTE:
To adjust the trim angle while the boat ismoving, use the power trim and tilt switchlocated on the remote control device or tillerhandle, if so equipped.

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 UPManual tilt model
1) Remove the fuel-line connection fromthe motor. (If the fuel connector is pro-vided on the motor.)
2) Place the tilt-lock lever in Release.
3) Hold the rear of the top cowling withone hand, tilt the engine up, and turnthe tilt-support lever to the locked posi-tion and support the engine.

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.

CRUISING IN OTHERCONDITIONS
CRUISING IN SALT WATERAfter operating in salt water, wash out thecooling-water passages with fresh water toprevent them from becoming clogged-upwith salt deposits.NOTE:
Refer to cooling system flushing instructionsin “TRANSPORTING AND STORING OUT-BOARD MOTOR”.
CRUISING IN TURBID WATERIt is strongly recommended that the optionalchromium-plated water-pump kit beinstalled if the outboard is to be used in tur-bid (muddy) water conditions.

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.

STORING OUTBOARD MOTORWhen storing your outboard motor for pro-longed periods of time (2 months or longer),several important procedures must be per-formed to prevent expensive damage.It is advisable to have your outboard ser-viced by an authorized Yamaha dealer priorto storage. However, the following proce-dures can be performed by the owner with aminimum of tools.
cC8 Do not place the engine on its side
before the cooling water has drainedfrom it completely, or water may enterthe cylinder through the exhaust portand cause problems.8 Store the engine in a dry, well-ventilat-
ed place, not in direct sunlight.
EMU01508
1) Wash the motor body using freshwater. (Refer to “MOTOR EXTERIOR”for details.)
2) Remove the fuel-line connection(s)from the motor or shut off the fuelvalve, if equipped.
3) Run the engine at idling speed whilesupplying fresh water to flush the cool-ing-water passages. Continue until thefuel system becomes empty and theengine stops. (Refer to “FLUSHINGCOOLING SYSTEM” for details.)
4) For electric start models, remove thebattery. (Refer to “DISCONNECTINGTHE BATTERY” for details.)
5) Drain the cooling water completely outof the motor.Clean the body thoroughly.
6) Remove the spark plug(s).

7) Pour a teaspoonful of clean engine oilinto the cylinder(s).
8) Crank several times manually.9) Replace the spark plug(s).EMU00336
Fuel Tank1) Drain the fuel from the tank for a long
period of storage.2) Store the fuel tank in a dry, well-venti-
lated place, not in direct sunlight.

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.

When fitting the plug, always clean the gas-ket surface and use a new gasket. Wipe offany dirt from the threads and screw in thespark 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 pastfinger-tight. Have the spark plug adjusted tothe correct torque as soon as possible witha torque-wrench.

TEMPORARY ACTION INEMERGENCY
EMU01492
IMPACT DAMAGE
wThe outboard motor can be seriouslydamaged by a collision while operatingor trailering. Damage could make theoutboard motor unsafe to operate.
If the outboard motor hits any object in thewater, follow the procedure below.1) Stop the engine immediately.2) Inspect the control system and all com-
ponents for damage. Also, inspect theboat for damage.
3) Whether damage is found or not, returnto the nearest harbor slowly and care-fully.
4) Have a Yamaha dealer inspect the out-board motor before operating it again.
EMU00418
RUNNING SINGLE ENGINEUsing only one of the engines in case of anemergency, be sure to keep the unusedone tilted up and operate the other engineat low speed.
cCIf the boat is operated with one engine inthe water but not running, water may runinto the exhaust pipe due to wave action,causing engine trouble.
NOTE:
When you are maneuvering at low speed,such as near a dock, it is recommendedthat both engines be running with one inneutral gear if possible.

STARTER WILL NOT OPERATEIf the starter mechanism does not operate(engine cannot be cranked with the starter),the engine can be started with an emer-gency starter rope.
w8 Use this procedure only in an emer-
gency and only to return to port forrepairs.8 When the emergency starter rope is
used to start the engine, the start-in-gear protection device does not oper-ate. Make sure the gear shift lever/remote control lever is in neutral.Otherwise, the boat could unexpected-ly start to move, which could result inan accident.8 Be sure no one is standing behind you
when pulling the starter rope. It couldwhip behind you and injure someone.8 An unguarded rotating flywheel is very
dangerous. Keep loose clothing andother objects away when starting theengine. Use the emergency starterrope only as instructed. Do not touchthe flywheel or other moving partswhen the engine is running. Do notinstall the starter mechanism or topcowling after the engine is running.8 Do not touch the ignition coil, high
voltage wire, spark plug cap or otherelectrical components when starting ofoperating the motor. You could beshocked.
