SAFETY
INFORMATION
8 Before mounting or operating the outboard motor, read this entire manual.
Reading it should give you an understanding of the motor and its operation.
8 Before operating the boat, read any
owner’s or operator’s manuals supplied
with it and all labels. Be sure you understand each item before operating.
8 Do not overpower the boat with this
outboard motor. Overpowering the
boat could result in loss of control. The
rated power of the outboard should be
equal to or less than the rated horsepower capacity of the boat. If the rated
horsepower capacity of the boat is
unknown, consult the dealer or boat
manufacturer.
8 Do
not
modify
the
outboard.
Modifications could make the motor
unfit or unsafe to use.
8 Never operate after drinking alcohol or
taking drugs. About 50% of all boating
fatalities involve intoxication.
8 Have an approved personal flotation
device (PFD) on board for every occupant. It is a good idea to wear a PFD
whenever boating. At a minimum, children and non-swimmers should always
wear PFDs, and everyone should wear
PFDs when there are potentially hazardous 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 or
leaking fuel before starting the engine.
8 This product emits exhaust gases which
contain carbon monoxide, a colorless,
odorless gas which may cause brain
damage or death when inhaled.
Symptoms include nausea, dizziness,
and drowsiness. Keep cockpit and cabin
areas well ventilated. Avoid blocking
exhaust outlets.
8 Check throttle, shift, and steering for
proper operation before starting the
engine.
8 Attach the engine stop switch lanyard
to a secure place on your clothing, or
your arm or leg while operating. If you
accidentally leave the helm, the lanyard
will pull from the switch, stopping the
engine.
8 Know the marine laws and regulations
where you will be boating - and obey
them. Refer to the “RULES OF THE
ROAD” section for basic boating rules.
8 Stay informed about the weather.
Check weather forecasts before boating.
Avoid boating 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
when you return.
8 Use common sense and good judgment
when boating. Know your abilities, and
be sure you understand how your boat
handles under the different boating
conditions you may encounter. Operate
within your limits, and the limits of your
boat. Always operate at safe speeds,
and keep a careful watch for obstacles
and other traffic.
8 Always watch carefully for swimmers
during the engine operation.
8 Stay away from swimming areas.

BASIC BOATING RULES
(Rules of the road)
Just as there are rules which apply when
you are driving on streets and high ways,
there are waterway rules which apply
when you are driving your boat. These
rules are used internationally, and are
also enforced by the United States Coast
Guard and local agencies. You should be
aware of these rules, and follow them
whenever you encounter another vessel
on the water.
Several sets of rules prevail according to
geographic location, but are all basically
the same as the International Rules of the
Road. The rules presented here in your
Owner’s Manual are condensed, and have
been provided for your convenience only.
Consult your local U.S. Coast Guard
Auxiliary or Department of Motor
Vehicles for a complete set of rules governing the waters in which you will be
using your boat.
Stand-on vessel
The vessel with the right-of-way has the
duty to continue its course and speed,
except to avoid an immediate collision.
When you maintain your direction and
speed, the other vessel will be able to
determine how best to avoid you.
Give-way vessel
The vessel which does not have the rightof-way has the duty to take positive and
timely action to stay out of the way of the
Stand-On vessel. Normally, you should
not cross in front of the vessel with the
right-of-way. You should slow down or
change directions briefly and pass behind
the other vessel. You should always move
in such a way that the operator of the
other vessel can see what you are doing.
“The general prudential rule”
This rule is called Rule 2
International Rules and says,
the
‘In obeying and construing these
rules due regard shall be had to all
dangers of navigation and collision,
and to any special circumstances,
which may render a departure from
the above rules necessary in order to
avoid immediate danger.’
STEERING AND SAILING RULES AND
SOUND SIGNALS
Whenever two vessels on the water meet
one another, one vessel has the right-ofway; it is called the “stand-on” vessel.
The vessel which does not have the rightof-way is called the “give-way” or “burdened” vessel. These rules determine
which vessel has the right-of-way, and
what each vessel should do.
in
In other words, follow the standard rules
except when a collision will occur unless
both vessels try to avoid each other. If
that is the case, both vessels become
“Give-Way” vessels.
1-7
68J-9-12-1
3/27/01 1:33 PM
Page 13
E
RULES WHEN ENCOUNTERING
VESSELS
There are three main situations which you
may encounter with other vessels which
could lead to a collision unless the
Steering Rules are followed:
Meeting
(you are approaching another vessel
head-on)
Crossing
(you are traveling across the other
vessel’s path)
Overtaking
(you are passing or being passed by
another vessel)
In the following illustration, your boat is
in the center. You should give the right-ofway to any vessels shown in white area
(you are the Give-Way vessel). Any vessels in the shaded area must yield to you
(they are the Give-Way vessels). Both you
and the meeting vessel must alter course
to avoid each other.
side. This rule doesn’t apply if both of you
will clear one another if you continue on
your set course and speed.
102044
Crossing
When two power driven vessels are
crossing each other’s path close enough
to run the risk of collision, the vessel
which has the other on the starboard
(right) side must keep out of the way of
the other. If the other vessel is on your
right, you must keep out of its way; you
are the Give-Way vessel. If the other vessel is on your port (left) side, remember
that you should maintain course and
direction, provided the other vessel gives
you the right-of-way as it should.
102045
Meeting
If you are meeting another power vessel
head on, and are close enough to run the
risk of collision, neither of you has the
right-of-way! Both of you should alter
course to avoid an accident. You should
keep the other vessel on your port (left)
102046
Overtaking
If you are passing another vessel, you are
the “Give-Way” vessel. This means that
the other vessel is expected to maintain
its course and speed. You must stay out
1-8
68J-9-12-1
3/27/01 1:33 PM
Page 14
E
of its way until you are clear of it.
Likewise, if another vessel is passing you,
you should maintain your speed and
direction so that the other vessel can steer
itself around you.
OTHER SPECIAL SITUATIONS
There are three other rules you should be
aware of when driving your boat around
other vessels.
Narrow channels and bends
When navigating in narrow channels, you
should keep to the right when it is safe
and practical to do so. If the operator of a
power-driven vessel is preparing to go
around a bend that may obstruct the view
of other water vessels, the operator
should sound a prolonged blast on the
whistle (4 to 6 seconds). If another vessel
is around the bend, it too should sound
the whistle. Even if no reply is heard,
however, the vessel should still proceed
around the bend with caution. If you navigate such waters with your boat, you will
need to carry a portable air horn, available from local marine supply stores.
Fishing vessel right-of-way
All vessels which are fishing with nets,
lines or trawls are considered to be “fishing vessels” under the International
Rules. Vessels with trolling lines are not
considered fishing vessels. Fishing vessels have the right-of-way regardless of
position. Fishing vessels cannot, however, impede the passage of other vessels in
narrow channels.
Sailing vessel right-of-way
Sailing vessels should normally be given
the right-of-way. The exceptions to this
are:
1. When the sailing vessel is overtaking
the power-driven vessel, the powerdriven vessel has the right-of-way.
2. Sailing vessels should keep clear of
any fishing vessel.
3. In a narrow channel, a sailing vessel
should not hamper the safe passage
of a power-driven vessel which can
navigate only in such a channel.
Reading buoys and other markers
The waters of the United states are
marked for safe navigation by the lateral
system of buoyage. Simply put, buoys
and markers have an arrangement of
shapes, colors, numbers and lights to
show which side of the buoy a boater
should pass on when navigating in a particular direction. The markings on these
buoys are oriented from the perspective
of being entered from seaward (the
boater is going towards the port). This
means that red buoys are passed on the
starboard (right) side when proceeding
from open water into port, and black
buoys are to port (left) side. When navigating out of port, your position with
respect to the buoys should be reversed;
red buoys should be to port and black
buoys to starboard.
Many bodies of water used by boaters are
entirely within the boundaries of a particular state. The Uniform State Waterway
Marking System has been devised for
these waters. This system uses buoys and
signs with distinctive shapes and colors
to show regulatory or advisory information. These markers are white with black
letters and orange boarders. They signify
speed zones, restricted areas, danger
areas, and general information.

Remember, markings may vary by geographic location. Always consult local
boating authorities before driving your
boat in unfamiliar waters.

GASOLINE (PETROL)
Recommended gasoline:
Regular unleaded gasoline with a minimum octane rating of 86 (Pump
Octane Number) = (R+M)/2
If knocking or pinging occurs, use a different brand of gasoline or premium unleaded fuel.
EMU00027
Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing
methanol. Gasohol containing ethanol
can be used if ethanol content does not
exceed 10% and the fuel meets minimum
octane ratings. Gasohol containing
methanol is not recommended by
Yamaha because it can cause fuel system
damage or engine performance problems.
EMU00858
ENGINE OIL
Recommended engine oil:
YAMALUBE 2 STROKE OUTBOARD
OIL
If the recommended engine oil is not
available, another 2-stroke engine oil with
a NMMA-certified TC-W3 rating may be
used.

BATTERY REQUIREMENT
cC
Do not use a battery that does not meet
the specified capacity. If a battery which
differs from the specification is used, the
electrical system may perform poorly or
be overloaded, causing electrical system
damage.
Choose a battery which meets the following specifications.
Minimum cold crank performance
512 Amps at -17.8°C (0°F)
Minimum reserve capacity
182 Minutes at 26.7°C (80°F)
If any electrical accessories are used, use
a second battery to power them. Choose
a battery with the same capacity as the
one for the engine. If the engine’s battery
voltage drops to approximately 9 volts or
below during operation or while starting,
the electric fuel pump for the Electronic
Fuel Injection system will not operate.
The engine can not be started if battery
voltage is too low.
EMU01395
PROPELLER SELECTION
The performance of your outboard motor
will be critically affected by your choice of
propeller, as an incorrect choice could
adversely affect performance and could
also seriously damage the motor. Engine
speed depends on the propeller size and
boat load. If engine speed is too high or
too low for good engine performance,
this will have an adverse effect on the
engine.

E
Yamaha outboard motors are fitted with
propellers chosen to perform well over a
range of applications, but there may be
uses where a propeller with a different
pitch would be more appropriate. For a
greater operating load, a smaller-pitch
propeller is more suitable as it enables
the correct engine speed to be maintained. Conversely, a larger-pitch propeller is more suitable for a smaller operating load.
14-1/2x17-M

Yamaha dealers stock a range of propellers, and can advise you and install a
propeller on your outboard that is best
suited to your application.
NOTE:
At full throttle and under a maximum
boat load, the engine’s rpm should be
within the upper half of the full throttle
operating range, as listed in “SPECIFICATIONS” on page 4-1. Select a propeller
which fulfills this requirement.
If operating under conditions which allow
the engine’s rpm to rise above the maximum recommended range (such as light
boat loads), reduce the throttle setting to
maintain the rpm in the proper operating
range.

Engine Stop Lanyard Switch
The lock-plate 1 must be attached to the
engine stop lanyard switch for the engine
to run. The lanyard 2 should be attached
to a secure place on the operator’s clothing, or arm or leg. Should the operator fall
overboard or leave the helm, the lanyard
will pull out the lock plate, stopping ignition to the engine. This will prevent the
boat from running away under power.
w
8 Attach the lanyard to a secure place on
your clothing, your arm or leg while
operating.
8 Do not attach the lanyard to clothing
that could tear loose. Do not route the
lanyard in such a way that it could
become entangled, preventing it from
functioning.
8 Avoid accidentally pulling the lanyard
during normal operation. Loss of
engine power means the loss of most
steering control. Also, without engine
power, the boat could slow rapidly.
This could cause people and objects in
the boat to be thrown forward.
NOTE:
The engine cannot be started with the
lock-plate removed.

The power trim/tilt adjusts the motor
angle in relation to the transom. The
power trim/tilt switch is located on the
side of the bottom engine cowling.
Pushing the switch “UP” trims the motor
up, then tilts the motor up. Pressing the
switch “DN” tilts the motor down and
trims the motor down. When the switch
button is released, the motor will stop in
its current position.
w
Use the power trim/tilt switch located on
the bottom engine cowling only when
the boat is at a complete stop with the
engine off. Attempting to use the cowling-mounted power trim/tilt switch while
the boat is moving could increase the risk
of falling overboard and could distract
the operator, increasing the risk of collision with another boat or an obstacle.
NOTE:
Refer to the sections “ADJUSTING TRIM

cC
Incorrect engine height or obstructions to
smooth water flow (such as the design or
condition of the boat or accessories 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 buoyancy
of the boat, at rest, with its maximum
load. Check that the static water level on
the exhaust housing is low enough to prevent water entry into the powerhead,
when water rises due to waves when the
outboard is not running.

MOUNTING THE OUTBOARD
MOTOR
w
8 Overpowering 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 manufacturer.
8 The information presented in this section 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 experience and the specific boat/motor combination.
w
Improper mounting of the outboard
motor could result in hazardous conditions such as poor handling, loss of control, or fire hazards. Observe the following:
8 For permanently mounted models,
your dealer or other person experienced in proper rigging should mount
the motor. If you are mounting the
motor yourself, you should be trained
by an experienced person.
8 For portable models, your dealer or
other person experienced in proper outboard motor mounting should show
you how to mount your motor.
3-2
68J-9-12-3
3/26/01 4:16 PM
Page 4
E
Mount the outboard motor on the center
line (keel line) of the boat, and ensure that
the boat itself is well balanced. Otherwise,
the boat will be hard to steer. For boats
without a keel or which are asymmetrical,
consult your dealer.
1 Center line (keel line)
q
104016
EMU01566
Mounting Height
To run your boat at optimum efficiency,
the water-resistance (drag) of the boat
and outboard motor must be made as little as possible. The mounting height of
the outboard motor greatly affects the
water-resistance. If the mounting height is
too high, cavitation tends to occur, thus
reducing the propulsion and causing the
engine to overheat. If the mounting
height is too low, the water-resistance will
increase and thereby reduce engine efficiency. Mount the engine so the anti-cavitation plate is about 130 mm (5 in.) above
the bottom of the boat.
NOTE:
8 The optimum mounting height of the
outboard motor is affected by the
boat/motor combination. Test runs at
different heights can help determine the
optimum mounting height.
For further details, consult your
Yamaha dealer or boat manufacture to
determine the proper mounting height.
8 Refer to the section “TRIMMING OUTBOARD MOTOR” for instructions on
setting the trim angle of the outboard.

BREAKING IN (RUNNING IN)
ENGINE
Your new engine requires a period of
break-in (running-in) to allow mating surfaces of moving parts to wear-in evenly.
Correct break-in (running-in) will help
ensure proper performance and longer
engine life.
cC
Do not use fuel mixed
with oil during break-in
or under any circumstances.
000106
8 Failure to follow the break-in (runningin) procedure may result in reduced
engine life or even severe engine damage.
8 Do not use pre-mixed fuel in this
engine as it may cause carbon deposits
on the fuel injector thereby causing
engine trouble.
8 Follow the instructions for breakingin/running-in carefully.
Break-in (running-in) time:10 hours
NOTE:
The label pictured at left is to be left on
the top cowling until the break-in (running-in) procedure has been completed
and may be removed afterwards.
EMU01195

easy-planing boat, accelerate at full
throttle onto plane, then immediately
reduce the throttle to 3,000 r/min or
less.
Second hour:
Accelerate at full throttle onto plane,
then reduce engine speed to threequarter throttle (approximately 4,000
r/min). Vary engine speed occasionally. Run at full throttle for one minute,
then allow about 10 minutes of operation at three-quarter throttle or less to
let the engine cool.
Third through tenth hours:
Avoid operating at full throttle for
more than 5 minutes at a time. Let the
engine cool between full-throttle runs.
Vary engine speed occasionally.
After the first 10 hours:
Operate the engine normally.

Ring Free Fuel Additive
Gasoline is a precise blend of many different substances, each chosen to give certain characteristics. Gasoline blends have
been changing in recent years in
response to concerns about pollution and
resulting emissions regulations. One of
the most obvious changes has been the
elimination of lead from most fuels.
As gasoline has changed, the amount of
additives such as aromatics and oxygenates has increased. These additives
are important for the engines in passenger cars, but they can have detrimental
effects in marine engines, because of
increased deposits in the combustion
chamber. When enough deposits collect,
piston rings begin sticking. Performance
drops and engine wear increases dramatically.
While many additives available may
reduce deposits, Yamaha recommends
the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free
has repeatedly proven its ability to clean
combustion deposits from inside the
engine, notably the critical piston-ringland area, and fuel system components.
Follow product labeling for use instructions.

operating conditions. No fuel pre-mixing
is needed. Simply pour gasoline into the
fuel tank and oil into the oil tank.
Convenient indicators show the status of
the oil supply. Refer to the section “OIL
LEVEL INDICATOR” for details.
To fill the engine oil tank, proceed as follows:

that the boat is tightly moored and that
you can steer clear of any obstructions.
Be sure there are no swimmers in the
water near you.
8 When the air vent screw is loosened,
gasoline (petrol) vapor will be released.
Gasoline (petrol) is highly flammable,
and its vapors are flammable and
explosive. Refrain from smoking, and
keep away from open flames and
sparks while loosening the air vent
screw.
8 This product emits exhaust gases
which contain carbon monoxide, a colorless, odorless gas which may cause
brain damage or death when inhaled.

A continuous flow of water from the pilot
hole shows that the water pump is
pumping water through the cooling passages. If water is not flowing out of the
pilot hole at all times while the engine is
running, do not continue to run the
engine. Overheating and serious damage
could occur. Stop the engine and check
to see if the water inlet on the lower casing is blocked. If the problem cannot be

TRIMMING OUTBOARD
MOTOR
The trim angle of the outboard motor
helps determine the position of the bow
of the boat in the water. The correct trim
angle will help improve performance and
fuel economy while reducing strain on the
engine. The correct trim angle depends
upon the combination of boat, engine,
and propeller. Correct trim is also affected
by variables such as the load in the boat,
sea conditions, and running speed.
w
Excessive trim for the operating conditions (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 TRIM
ANGLE” for instructions on usage.

EMU01558
Bow Up
When the boat is on plane, a bow-up attitude results in less drag, greater stability
and efficiency. This is generally when the
keel line of the boat is up about 3 to 5
degrees. When trimmed out, the boat
may have more tendency to steer to one
side or the other. Compensate for this as
you steer. The trim tab can also be adjusted to help offset this effect.
q
105011
w
Too much trim-out puts the bow of the
boat too high in the water. Performance
and economy are decreased because the
hull of the boat is pushing the water and
there is more air drag.
Excessive trim-up can cause the propeller
to ventilate, which reduces performance
further. When trimmed-out too much, a
boat may “porpoise” (hop in the water),
which could throw the operator and passengers overboard.
EMU01559
Bow Down
When the bow of the boat is down, it is
easier to accelerate from a standing start
onto plane.
105013
e
105015
Too much trim-in causes the boat to
“plow” through the water, decreasing
fuel economy and making it hard to
increase speed.
Operating with excessive trim-in at higher
speeds also makes the boat unstable.
Resistance at the bow is greatly
increased, heightening the danger of
“bow steering” and making operation difficult and dangerous.

TILTING UP/DOWN
000516
If the engine will be stopped for some
time, or if the boat is moored in shallows,
the engine should be tilted up to protect
the propeller and casing from damage by
collision with obstructions, and also to
reduce salt corrosion.
cC
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.
w
Be sure all people are clear of the outboard motor when adjusting the tilt
angle, also be careful not to pinch any
body parts between the drive unit and
engine bracket.
w
Leaking fuel is a fire hazard. Disconnect
the fuel line or close the fuel cock if the
engine will be tilted for more than a few
minutes. Otherwise, fuel may leak. (If the
fuel connector is provided on the motor.)

close the air vent screw and fuel cock to
prevent fuel from leaking.
EMU00326
TRAILERING OUTBOARD MOTOR
102074
The motor should be trailered and stored
in the normal running position. If there is
insufficient road clearance in this position,
then trailer the motor in the tilt position
using a motor support device such as a
transom saver bar.
For further details, consult your Yamaha
dealer.
w
8 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.
8 DO NOT fill fuel container to maximum
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
hazard.
cC
Do 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.

STORING OUTBOARD MOTOR
When storing your Yamaha outboard for
prolonged periods of time, (2 months or
longer), several important procedures
must be performed to prevent expensive
damage. This is especially important for
your Yamaha oil injection systemequipped outboard due to the lean oil
ratios used at idle prior to shutting the
engine off for the season.
It is advisable to have your outboard serviced by an authorized Yamaha dealer
prior to storage. However, the following
procedures can be performed by you, the
owner, with a minimum of tools.
q
cC
000100
8 Do not use any chemical goods containing Silicon, Phosphorus or Lead.
Otherwise, the oxygen sensor for
Electronic Fuel Injection system could
be damaged. For the detail, consult
your Yamaha dealer to use chemical
goods for storage.
8 Drain the remaining gasoline from the
vapor separator. Gasoline left in the
vapor separator 1 for a prolonged period of time will break down and possibly cause damage to the fuel line.
EMU00335
Filling Fuel Tank
Fill the fuel tank with fresh fuel and add
one ounce of “Yamaha Fuel Conditioner
and Stabilizer” (Part No. LUB-FUELC-1200) to each gallon of fuel.
NOTE:
The use of “Yamaha Fuel Conditioner and
Stabilizer” eliminates the need to drain

CLEANING AND ADJUSTING SPARK
PLUG
w
When removing or installing a spark plug,
be careful not to damage the insulator. A
damaged insulator could allow external
sparks, which could lead to explosion or
fire.
The spark plug is an important engine
component and is easy to inspect. The
condition of the spark plug can indicate
something about the condition of the
engine. For example, if the center electrode porcelain is very white, this could
indicate an intake air leak or carburetion
problem in that cylinder. Do not attempt
to diagnose any problems yourself.
Instead, take the outboard motor to a
Yamaha dealer. You should periodically
remove and inspect the spark plug
because heat and deposits will cause the
spark plug to slowly break down and
erode. If electrode erosion becomes
excessive, or if carbon and other deposits
are excessive, you should replace the
spark plug with another of the correct
type.
Standard spark plug:
Refer to “SPECIFICATIONS”, page 4-1.
Before fitting the spark plug, measure the
electrode gap with a wire thickness
gauge; adjust the gap to specification if
necessary.

E
Spark plug gap:
Refer to “SPECIFICATIONS”, page 4-1.
When fitting the plug, always clean the
gasket surface and use a new gasket.
Wipe off any dirt from the threads and
screw in the spark plug to the correct
torque.
Spark plug torque:
Refer to “SPECIFICATIONS”, page 4-1.
NOTE:
If a torque-wrench is not available when
you are fitting a spark plug, a good estimate of the correct torque is 1/4 to 1/2 a
turn past finger-tight. Have the spark plug
adjusted to the correct torque as soon as
possible with a torque-wrench.

CLEANING COOLING-WATER
PASSAGES
Flushing device equipped model
Perform this procedure right after operation for the most thorough flushing.
1) After shutting off the engine, unscrew
the garden-hose connector 2 from
the fitting 1 on the bottom cowling.
2) Screw the garden-hose connector 2
onto a garden hose 3 which is connected to a fresh-water supply.
3) With the engine off, turn on the water
tap and let the water flush through
the cooling passages for about 15
minutes. Turn off the water and disconnect the garden hose 3.
4) When flushing is complete, reinstall
the garden-hose connector 2 on the
fitting 1 on the bottom cowling.
Tighten the connector securely.
q
w e
cC
000524
Do not leave the garden-hose connector
loose on the bottom cowling fitting or let
the hose hang free during normal operation. Water will leak out of the connector
instead of cooling the engine, which can
cause serious overheating. Be sure the
connector is tightened securely on the fitting after flushing the engine.
NOTE:
8 When flushing the engine with the boat
in the water, tilting up the engine until it
is completely out of the water will
achieve better results.
8 Refer to cooling system flushing
instructions in “TRANSPORTING AND
STORING OUTBOARD MOTOR”.

Cleaning the Outboard Motor
After use, wash the exterior of the outboard with fresh water.
Flush the cooling system with fresh
water.
NOTE:
Refer to Flushing Cooling System instructions in “TRANSPORTING AND STORING
OUTBOARD MOTOR”.
EMU00412
Checking Painted Surface of Motor
Check the motor for scratches, nicks, or
flaking paint. Areas with damaged paint
are more likely to corrode. If necessary,
clean and paint the areas. A touch-up
paint is available from a Yamaha dealer.
EMU00413
COATING THE BOAT BOTTOM
102025
A clean hull improves boat performance.
The boat bottom should be kept as clean
of marine growths as possible. If necessary, the boat bottom can be coated with
an anti-fouling paint approved for your
area to inhibit marine growth.
Do not use anti-fouling paint which
includes copper or graphite. These paints
can cause more rapid engine corrosion.

STARTER WILL NOT OPERATE
If the starter mechanism does not operate
(engine cannot be cranked with the
starter), the engine can be manually started with an emergency starter rope.
However, the engine can not be manually
started if the battery voltage is low. If the
battery is discharged to 9 volts or below,
the electrical fuel pump will not operate.
w
8 Use this procedure only in an emergency and only to return to port for
repairs.
8 When the emergency starter rope is
used to start the engine, the start-ingear protection device does not operate. Make sure the remote control lever
is in neutral. Otherwise, the boat could
unexpectedly 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 suffer a
serious electrical shock.

IMPORTANT WARRANTY INFORMATION FOR U.S.A. AND
CANADA
Welcome to the Yamaha Family!
Congratulations on the purchase of your new Yamaha marine power. Yamaha is committed to exceptional customer satisfaction, and we want your ownership experience to be
a satisfying one. Please read the following warranty information to help ensure satisfaction with your Yamaha.
Yamaha is ready to stand behind your purchase with strong warranty coverage. To be sure
you receive all the benefits of warranty, please take the following steps:
1. Be sure your new Yamaha is registered for warranty. Your boat dealer should do this at
the time of sale. Make sure your dealer gives you a copy of the completed Yamaha registration card for your records. If you are unsure whether or not your Yamaha is registered,
complete the Warranty Registration card found inside the cover of the Owner’s Manual.
Mail it to the distributor for the country in which you live (see step 6 for the correct
address). If your Yamaha is not properly registered, a warranty repair could be unnecessarily delayed while registration records are checked.
2. Read the Limited Warranty statement which follows these instructions. This warranty
applies to Yamaha outboard motors sold in the United States, whether purchased separately or when supplied as original equipment by a boat builder. The terms also apply to
original equipment packages sold in Canada, with coverage provided by Yamaha Motor
Canada (see ``Warranty Guide’’ for Canadian models). This warranty explains the conditions of the warranty, including the obligations that your dealer and you as the owner
have under the warranty. For example, your Yamaha outboard must receive a proper
pre-delivery inspection (PDI) by the selling dealer. Failure to take this important step
could jeopardize warranty coverage!
3. If you need warranty repairs, you must take your Yamaha outboard to an authorized
Yamaha outboard dealer. Be aware that not all selling boat dealers are authorized
Yamaha dealers. Only authorized dealers have the factory training, special tools, and
Yamaha support needed to perform warranty repairs.
4. If you are away from home, or your selling dealer is not an authorized Yamaha dealer,
use the following toll-free numbers to find the nearest Yamaha dealer.
United States Dealer Locations: 1-800-692-6242
Canada Dealer Locations:
1-800-267-8577

5. Your warranty applies specifically to repairs made in the country of purchase. If your
U.S.-purchased Yamaha needs warranty service while in Canada, or your Canadian purchased Yamaha needs service while in the United States, Yamaha will assist the local
dealer whenever possible. However, some products available in one country may not be
sold or serviced in the other.
6. If you need any additional information about your Yamaha or warranty coverage which
your dealer cannot provide, please contact us directly.

A.
May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them?
Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s and Service Manuals. We do recommend,

Q.
A.
Will the warranty be void or canceled if I do not operate or maintain my new outboard exactly as specified in the Owner’s Manual?
