SAFETY
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
outboard motor. Overpowering theboat could result in loss of control. Therated power of the outboard should beequal to or less than the rated horse-power capacity of the boat. If the ratedhorsepower capacity of the boat isunknown, consult the dealer or boatmanufacturer.8 Do not modify the outboard. Modifica-
tions could make the motor unfit orunsafe to use.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 is highly flammable, and its
vapors are flammable and explosive.Handle and store gasoline carefully.Make sure there are no gas fumes orleaking fuel before starting the engine.

Stand-on Vessel
The vessel with the right-of-way has theduty to continue its course and speed,except to avoid an immediate collision.When you maintain your direction andspeed, the other vessel will be able todetermine how best to avoid you.
Give-way Vessel
The vessel which does not have theright-of-way has the duty to take posi-tive and timely action to stay out of theway of the Stand-On vessel. Normally,you should not cross in front of the ves-sel with the right-of-way. You shouldslow down or change directions brieflyand pass behind the other vessel. Youshould always move in such a way thatthe operator of the other vessel can seewhat you are doing.
“The general prudential rule”
This rule is called Rule 2 in the Inter-national Rules and says,
‘In obeying and construing theserules due regard shall be had to alldangers of navigation and collision,and to any special circumstances,which may render a departure fromthe above rules necessary in order toavoid immediate danger.’
In other words, follow the standard rulesexcept when a collision will occur unlessboth vessels try to avoid each other. Ifthat is the case, both vessels become“Give-Way” vessels.
EMB40010
BASIC BOATING RULES
(Rules of the road)
Just as there are rules which applywhen you are driving on streets andhigh ways, there are waterway ruleswhich apply when you are driving yourboat. These rules are used international-ly, and are also enforced by the UnitedStates Coast Guard and local agencies.You should be aware of these rules, andfollow them whenever you encounteranother vessel on the water.
Several sets of rules prevail according togeographic location, but are all basicallythe same as the International Rules ofthe Road. The rules presented here inyour Owner’s Manual are condensed,and have been provided for your conve-nience only. Consult your local U.S.Coast Guard Auxiliary or Department ofMotor Vehicles for a complete set ofrules governing the waters in which youwill be using your boat.
STEERING AND SAILING RULES
AND SOUND SIGNALS
Whenever two vessels on the watermeet one another, one vessel has theright-of-way; it is called the “stand-on”vessel. The vessel which does not havethe right-of-way is called the “give-way”or “burdened” vessel. These rules deter-mine which vessel has the right-of-way,and what each vessel should do.

RULES WHEN ENCOUNTERING
VESSELS
There are three main situations whichyou may encounter with other vesselswhich could lead to a collision unlessthe Steering Rules are followed:Meeting
(you are approaching another vesselhead-on)
Crossing
(you are travelling across the othervessel’s path)
Overtaking
(you are passing or being passed byanother vessel)
In the following illustration, your boat isin the center. You should give the right-of-way to any vessels shown in whitearea (you are the Give-Way vessel). Anyvessels in the shaded area must yield toyou (they are the Give-Way vessels).Both you and the meeting vessel mustalter course to avoid each other.
Meeting
If you are meeting another power vesselhead on, and are close enough to runthe risk of collision, neither of you hasthe right-of-way! Both of you shouldalter course to avoid an accident. You
102045
should keep the other vessel on yourport (left) side. This rule doesn’t apply ifboth of you will clear one another if youcontinue on your set course and speed.
Crossing
When two power driven vessels arecrossing each other’s path close enoughto run the risk of collision, the vesselwhich has the other on the starboard(right) side must keep out of the way ofthe other. If the other vessel is on yourright, you must keep out of its way; youare the Give-Way vessel. If the othervessel is on your port (left) side, remem-ber that you should maintain course anddirection, provided the other vesselgives you the right-of-way as it should.
Overtaking
If you are passing another vessel, youare the “Give-Way” vessel. This meansthat the other vessel is expected to

1. When the sailing vessel is overtakingthe power-driven vessel, the power-driven vessel has the right-of-way.
2. Sailing vessels should keep clear ofany fishing vessel.
3. In a narrow channel, a sailing vesselshould not hamper the safe passageof a power-driven vessel which cannavigate only in such a channel.
Reading Buoys and Other Markers
The waters of the United states aremarked for safe navigation by the lateralsystem of buoyage. Simply put, buoysand markers have an arrangement ofshapes, colors, numbers and lights toshow which side of the buoy a boatershould pass on when navigating in aparticular direction. The markings onthese buoys are oriented from the per-spective of being entered from seaward(the boater is going towards the port).This means that red buoys are passedon the starboard (right) side when pro-ceeding from open water into port, andblack buoys are to port (left) side. Whennavigating out of port, your positionwith respect to the buoys should bereversed; red buoys should be to portand black buoys to starboard.
Many bodies of water used by boatersare entirely within the boundaries of aparticular state. The Uniform StateWaterway Marking System has beendevised for these waters. This systemuses buoys and signs with distinctiveshapes and colors to show regulatory oradvisory information. These markers arewhite with black letters and orangeboarders. They signify speed zones,restricted areas, danger areas, and gen-eral information.
maintain its course and speed. You muststay out of its way until you are clear ofit. Likewise, if another vessel is passingyou, you should maintain your speedand direction so that the other vesselcan steer itself around you.OTHER SPECIAL SITUATIONS
There are three other rules you shouldbe aware of when driving your boataround other vessels.
Narrow Channels and Bends
When navigating in narrow channels,you should keep to the right when it issafe and practical to do so. If the opera-tor of a power-driven vessel is preparingto go around a bend that may obstructthe view of other water vessels, theoperator should sound a prolongedblast on the whistle (4 to 6 seconds). Ifanother vessel is around the bend, it tooshould sound the whistle. Even if noreply is heard, however, the vesselshould still proceed around the bendwith caution. If you navigate suchwaters with your boat, you will need tocarry a portable air horn, available fromlocal marine supply stores.
Fishing Vessel Right-of-way
All vessels which are fishing with nets,lines or trawls are considered to be“fish-ing vessels” under the InternationalRules. Vessels with trolling lines are notconsidered fishing vessels. Fishing ves-sels have the right-of-way regardless ofposition. Fishing vessels cannot, howev-er, impede the passage of other vesselsin narrow channels.
Sailing Vessel Right-of-way
Sailing vessels should normally begiven the right-of-way. The exceptionsto this are:

PROPELLER SELECTION
The performance of your outboard motorwill be critically affected by your choiceof propeller, 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 ortoo low for good engine performance,this will have an adverse effect on theengine.
Yamaha outboard motors are fitted withpropellers chosen to perform well over arange of applications, but there may beuses where a propeller with a differentpitch would be more appropriate. For agreater operating load, a smaller-pitchpropeller is more suitable as it enablesthe correct engine speed to be main-tained. Conversely, a larger-pitch pro-peller is more suitable for a smaller oper-ating load.
Yamaha dealers stock a range of pro-pellers, and can advise you and install apropeller on your outboard that is bestsuited to your application.

Yamaha outboard motors or Yamahaapproved remote control units areequipped with start-in-gear protectiondevice(s). This feature permits the engineto be started only when it is Neutral.Always select Neutral before starting theengine.
NOTE:
At full throttle and under a maximumboat load, the engine’s rpm should bewithin the upper half of the full throttleoperating range, as listed in “SPECIFICA-TIONS” on page 4-1. Select a propellerwhich fulfills this 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.

cCIncorrect engine height or obstructions
to smooth water flow (such as the
design or condition of the boat or acce-
ssories such as transom ladders/depth
finder transducers) can create airborne
water spray while the boat is cruising.
Severe engine damage may result if the
motor is operated continuously in the
presence of airborne water spray.
NOTE:
During water testing check the buoyancyof the boat, at rest, with its maximumload. Check that the static water level onthe exhaust housing is low enough toprevent water entry into the powerhead,when water rises due to waves when theoutboard is not running.

MOUNTING THE OUTBOARD
MOTOR
wImproper mounting of the outboard
motor could result in hazardous condi-
tions such as poor handling, loss of con-
trol, or fire hazards. Observe the follow-
ing:
8 The information presented in this sec-
tion is intended as reference only. It is
not possible to provide complete
instructions for every possible
boat/motor combination. Proper
mounting depends in part on experi-
ence and the specific boat/motor com-
bination.
8 Your dealer or other person experi-
enced in proper rigging should mount
the motor. If you are mounting the
motor yourself, you should be trained
by an experienced person. [permanent
mounted type]
8 Your dealer or other person experi-
enced in proper outboard motor
mounting should show you how to
mount your motor. [portable type]
Mount the outboard motor on the centerline (keel line) of the boat, and ensurethat the boat itself is well balanced. Oth-erwise, the boat will be hard to steer. Forboats without a keel or which are asym-metrical, consult your dealer.

wOverpowering a boat may cause severe
instability. Do not install an outboard
motor with more horsepower than the
maximum rating on the capacity plate of
the boat. If the boat does not have a
capacity plate, consult the boat manufac-
turer.
EMU01298
Mounting Height
To run your boat at optimum efficiency,the water-resistance (drag) of the boatand outboard motor must be made as lit-tle as possible. The mounting-height ofthe outboard motor greatly affects thewater-resistance. If the mounting-heightis too high, cavitation tends to occur, thusreducing the propulsion; and if the pro-peller tips cut the air, the engine speedwill rise abnormally and cause the engineto overheat. If the mounting-height is toolow, the water-resistance will increaseand thereby reduce engine efficiency.Mount the engine so that the anti-cavita-tion plate is between the bottom of theboat and a level 25 mm (1 in.) below it.NOTE:
8 The optimum mounting height of theoutboard motor is affected by theboat/motor combination and thedesired use. Test runs at differentheights can help determine the opti-mum mounting height.8 Refer to the section “TRIMMING OUT-
BOARD MOTOR” for instructions onsetting the trim angle of the outboard.

CLAMPING THE OUTBOARD
MOTOR
1) Place the outboard on the transomso that it is positioned as close to thecenter as possible. Tighten the tran-som clamp screws evenly andsecurely. Check the clamp-screws fortightness occasionally during opera-tion of the motor as they can workloose due to engine vibration.
wLoose clamp screws could allow the
motor to move on the transom or fall
off the transom. This could cause loss of
control and serious injury. Make sure
the transom screws are tightened
securely.
Occasionally check the screws for tight-
ness during operation.
2) An engine restraint cable or chainshould be used. Attach one end tothe engine restraint cable attachmentpoint and the other to a securemounting point on the boat. Other-wise, the engine could be completelylost if it accidentally falls off the tran-som.

FILLING FUEL
1) Put the outboard in the tilt-downposition. Remove the fuel tank cap.
2) Use a funnel if the nozzle on the fuelcan or pump is not small enough orlong enough to fit into the mouth ofthe fuel tank.
3) Fill the fuel tank carefully.4) Close the cap securely after refuel-
ing. Wipe up any spilled fuel.
Ring Free Fuel Additive
Gasoline is a precise blend of many dif-ferent substances, each chosen to givecertain characteristics. Gasoline blendshave been changing in recent years inresponse to concerns about pollutionand resulting emissions regulations.One of the most obvious changes hasbeen the elimination of lead from mostfuels.
As gasoline has changed, the amount ofadditives such as aromatics and oxy-genates has increased. These additivesare important for the engines in passen-ger cars, but they can have detrimentaleffects in marine engines, particularly 2-cycle outboards because of increaseddeposits in the combustion chamber.When enough deposits collect, pistonrings begin sticking. Performance dropsand engine wear increases dramatically.
Fuel tank capacity:Refer to SPECIFICATIONS, Page 4-1.

TRIMMING OUTBOARD
MOTOR
The trim angle of the outboard motorhelps determine the position of the bowof the boat in the water. The correct trimangle will help improve performance andfuel economy while reducing strain onthe engine. The correct trim angledepends upon the combination of boat,engine, and propeller. Correct trim is alsoaffected by variables such as the load inthe boat, sea conditions, and runningspeed.
wExcessive trim for the operating condi-
tions (either trim up or trim down) can
cause boat instability and can make
steering the boat more difficult. This
increases the possibility of an accident. If
the boat begins to feel unstable or is
hard to steer, slow down and/or readjust
the trim angle.
NOTE:
Refer to the section “ADJUSTING TRIMANGLE” for instructions on usage.

Manual tilt model
There are 4 or 5 holes provided in theclamp bracket to adjust the outboardmotor trim angle.1) Stop the engine.2) Remove the trim angle adjusting rod
1 from the clamp bracket while tilt-ing the motor up slightly.
3) Reposition the rod in the desiredhole.
To raise the bow (“trim-out”), move therod away from the transom.To lower the bow (“trim-in”), move therod toward the transom.Make test runs with the trim set to differ-ent angles to find the position that worksbest for your boat and operating condi-tions.
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 speed
gradually and watch for any signs of
instability or control problems. Improp-
er trim angle can cause loss of control.
NOTE:
The outboard motor trim angle can bechanged approximately 4 degrees byshifting the trim adjusting-rod one hole.

Bow Up
When the boat is on plane, a bow-up atti-tude result 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 boatmay have more tendency to steer to oneside or the other. Compensate for this asyou steer. The trim tab can also beadjusted to help offset this effect.
Too much trim-out puts the bow of theboat too high in the water. Performanceand economy are decreased because thehull of the boat is pushing the water andthere is more air drag.Excessive trim-up can cause the propellerto ventilate, which reduces performancefurther. When trimmed-out too much, aboat may “porpoise” (hop in the water),which could throw the operator and pas-sengers overboard.EMU00283
Bow Down
When the bow of the boat is down, it iseasier to accelerate from a standing startonto plane.
Too much trim-in causes the boat to“plow” through the water, decreasingfuel economy and making in hard toincrease speed.Operating with excessive trim-in at high-er speeds also makes the boat unstable.Resistance at the bow is greatlyincreased, heightening the danger of“bow steering” and making operationdifficult and dangerous.

cruising system. The tilt-lock mecha-
nism does not work while the shallow
water cruising system is being used.
Hitting an underwater obstacle could
cause the engine to lift out of the
water, resulting in loss of control.
8 Use extra care when operating in
reverse. Too much reverse thrust can
cause the engine to lift out of the
water, increasing the chance of acci-
dent and personal injury.

TILTING UP/DOWN
If the engine will be stopped for sometime, or if the boat is moored in shallows,the engine should be tilted up to protectthe propeller and casing from damage bycollision with obstructions, and also toreduce salt corrosion.
cC8 Before tilting the motor, follow the
procedures under “STOPPING
ENGINE”. Never tilt the motor while
the engine is running. Severe damage
from overheating can result.
8 Do not tilt up the engine by pushing
the steering handle as this could break
the handle.
8 Keep the power unit higher than the
propeller at all times. Otherwise, water
can run into the cylinder, causing dam-
age.
8 The outboard cannot be tilted when in
Reverse, or when the outboard is
turned 180° (facing to the rear).
wBe sure all people are clear of the out-
board motor when adjusting the tilt
angle, also be careful not to pinch any
body parts between the drive unit and
engine bracket.
wLeaking fuel is a fire hazard. Tighten the
air-vent screw and place the fuel cock in
the closed position if the engine will be
tilted for more than a few minutes. Oth-
erwise, fuel may leak.

TRAILERING OUTBOARD MOTOR
The motor should be trailered andstored in the normal running position. Ifthere is insufficient road clearance inthis position, then trailer the motor inthe tilt position using a motor supportdevice such as a transom saver bar.
cCDo not use the tilt support lever/knob
when trailering the boat. The outboard
motor could shake loose from the tilt
support and fall. If the motor can not be
trailered in the down position, use an
additional support device to secure it in
the up position.
w8 Never get under the lower unit while
it is tilted, even if a motor support bar
is used. Severe injury could occur if
the outboard accidentally falls.
8 USE CARE when transporting fuel
tank, whether in a boat or car.
DO NOT fill fuel container to maxi-
mum capacity.
Gasoline will expand considerably as
it warms up and can build up pressure
in the fuel container. This can cause
fuel leakage and a potential fire haz-
ard.

CLEANING AND ADJUSTING SPARK
PLUG
wWhen removing or installing a spark
plug, be careful not to damage the insu-
lator. A damaged insulator could allow
external sparks, which could lead to
explosion or fire.
The spark plug is an important enginecomponent and is easy to inspect. Thecondition of the spark plug can indicatesomething about the condition of theengine. For example, if the center elec-trode porcelain is very white, this couldindicate an intake air leak or carburetionproblem in that cylinder. Do not attemptto diagnose any problems yourself.Instead, take the outboard motor to aYamaha dealer. You should periodicallyremove and inspect the spark plugbecause heat and deposits will cause thespark plug to slowly break down anderode. If electrode erosion becomesexcessive, or if carbon and other depositsare excessive, you should replace thespark plug with another of the correcttype.
Before fitting the spark plug, measure theelectrode gap with a wire thicknessgauge; adjust the gap to specification ifnecessary.
Standard spark plug:Refer to “SPECIFICATIONS”, page 4-1.
Spark plug gap:Refer to “SPECIFICATIONS”, page 4-1.

When fitting the plug, always clean thegasket surface and use a new gasket.Wipe off any dirt from the threads andscrew in the spark plug to the correcttorque.
NOTE:
If a torque-wrench is not available whenyou are fitting a spark plug, a good esti-mate of the correct torque is 1/4 to 1/2 aturn past finger-tight. Have the spark plugadjusted to the correct torque as soon aspossible with a torque-wrench.

CHECKING PROPELLER; SHEAR PIN
AND COTTER PIN
wYou could be seriously injured if the
engine accidentally starts while you are
near the propeller.
8 Before inspecting, removing or
installing the propeller, remove the
spark plug caps from the spark plugs.
Also, put the shift control in Neutral,
put the main switch in the “OFF”
position and remove the key, and
remove the lanyard from the engine
stop switch. Turn off the battery cut-
off switch if your boat has one.
8 Do not use your hand to hold the pro-
peller when loosening or tightening
the propeller nut. Put a wood block
between the cavitation plate and the
propeller to prevent the propeller
from turning.
2
1) Check each of the propeller bladesfor wear, erosion from cavitation orventilation, or other damage.
2) Check the shear pin for wear or dam-age. The shear pin is designed tobreak if the propeller hits a hardunderwater obstacle to help protectthe propeller and drive mechanism.The propeller will then spin freely onthe shaft. If this happens, the shearpin must be replaced.
3) Check for fish line winding aroundthe propeller shaft. Check the pro-peller shaft oil seal for damage.

STARTER WILL NOT OPERATE
If the starter mechanism does not oper-ate (engine cannot be cranked with thestarter), the engine can be started withan emergency starter rope.
w8 Use this procedure only in an emer-
gency and only to return to port for
repairs.
8When 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 is
in neutral. Otherwise, the boat could
unexpectedly start to move, which
could result in an accident.
8 2-hp model: The propeller rotates
whenever the engine is running. Do
not move the throttle control lever
from the start position during warm-
up. Otherwise, the boat could unex-
pectedly start to move, which could
result in an accident.
8 Be sure no one is standing behind you
when pulling the starter rope. It could
whip behind you and injure someone.
8 An unguarded rotating flywheel is
very dangerous. Keep loose clothing
and other objects away when starting
the engine. Use the emergency starter
rope only as instructed. Do not touch
the flywheel or other moving parts
when the engine is running. Do not
install the starter mechanism or top
cowling after the engine is running.
8 Do not touch the ignition coil, high
voltage wire, spark plug cap or other
electrical components when starting
or operating the motor. You could be
shocked.
