Before mounting or operating the outboard motor, read this entire manual.
Reading it should give you an understanding of the motor and its operation.
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.
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.
Do not modify the outboard. Modifications
could make the motor unfit or unsafe to
use.
Never operate after drinking alcohol or
taking drugs. About 50% of all boating
fatalities involve intoxication.
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.
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.

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.
Check throttle, shift, and steering for
proper operation before starting the
engine.
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.
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.
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
Tell someone where you are going: leave
a Float Plan with a responsible person.
Be sure to cancel the Float Plan when
you return.
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.
Always watch carefully for swimmers during the engine operation.
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 right-ofway 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 in the International
Rules and says,
‘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 right-of-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 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
E_69J10.book Page 8 Monday, May 28, 2001 9:52 AM
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-of-way
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.
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 rightof-way! Both of you should alter course to
avoid an accident. You should keep the
other vessel on your port (left) side. This
rule doesn’t apply if both of you will clear
one another if you continue on your set
course and speed.
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.
Overtaking
If you are passing another vessel, you are
the “Give-Way” vessel. This means that the
1-8
E_69J10.book Page 9 Monday, May 28, 2001 9:52 AM
E
other vessel is expected to maintain its
course and speed. You must stay out 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 powerdriven 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-ofway 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.
1-9

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

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.
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.
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.

●
Attach the lanyard to a secure place on
your clothing, your arm or leg while
operating.
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.
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.

of water (salt, fresh, and contaminate levels), air temperature and humidity, cleanliness of the boat bottom, engine mounting
height, skill of the operator, and individual
gasoline formulation (winter or summer
fuel and amount of additives).
● The Yamaha digital speedometer and fuel
management meter calculates speed,
miles traveled, and fuel economy by water
movement at the stern of the boat. This
distance can vary greatly from the actual
distance traveled because of water currents, sea swells, and the condition of the
water speed sensor (partially plugged or
damaged).
● Individual engines may slightly vary in
their fuel consumption due to manufacturing variations. These variations can be
even greater if the engines are of different
year models. In addition, variations in propellers, even of the same basic dimensions of the same design, can also cause
a slight variation in fuel consumption.

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.
WARNING
@
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.

WARNING
@
●
●
●
Be sure all people are clear of the outboard motor when adjusting the trim/
tilt angle, also be careful not to pinch
any body parts between the drive unit
and clamp bracket.
Use caution when trying a trim position for the first time. Increase speed
gradually and watch for any signs of
instability or control problems.
Use the power trim/tilt switch located
on the bottom engine cowling (if
equipped) only when the boat is at a
complete stop with the engine off.
@
The outboard motor trim angle can be
adjusted operating the power trim/tilt switch
1.
To raise the bow (“trim-out”), push the switch
UP.
To lower the bow (“trim-in”), push the switch
DN.
Make test runs with the trim set to different
angles to find the position that works best for
your boat and operating conditions.
NOTE:
To adjust the trim angle while the boat is
moving, use the power trim and tilt switch
located on the remote control box.

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.
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.
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
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.
WARNING
@
●
●
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.
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.)
@
CAUTION:
@
●
●
@
3-14
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.
To prevent the cooling water passages
from becoming frozen when the ambient temperature is 5°C or below, tilt up
the motor after it has been stopped 30
seconds or more.

TRANSPORTING AND
STORING OUTBOARD MOTOR
WARNING
@
Leaking fuel is a fire hazard. When transporting and storing the outboard motor,
close the air vent screw and fuel cock to
prevent fuel from leaking.
@
EMU00326¯
TRAILERING OUTBOARD MOTOR
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.
WARNING
@
●
●
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.
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.
@
CAUTION:
@
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.

●
●
4-4
To prevent problems which can be
caused by oil entering the cylinder
from the sump, keep the engine in the
vertical position when transporting
and storing it.
Do not place the engine on its side
before the cooling water has drained
from it completely, or water may enter
the cylinder through the exhaust port
and cause problems.
Store the engine in a dry, well-ventilated place, not in direct sunlight.
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.

CLEANING AND ADJUSTING SPARK
PLUG
WARNING
@
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.
Spark plug gap:
Refer to “SPECIFICATIONS”, page 4-1.
4-14
E_69J10.book Page 15 Monday, May 28, 2001 9:52 AM
E
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.

Using only one of the engines in case of an
emergency, be sure to keep the unused one
tilted up and operate the other engine at low
speed.
CAUTION:
@
If the boat is operated with one engine in
the water but not running, water may run
into 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 recommended that
both engines be running with one in neutral
gear if possible.

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
E_69J10.book Page 2 Monday, May 28, 2001 9:52 AM
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.

IMPORTANT WARRANTY INFORMATION IF YOU USE YOUR
YAMAHA OUTSIDE U.S.A. OR 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.
This model was manufactured as a U.S.A. specification model, and the warranty statement
shown in this manual is for market. To receive the benefits of the warranty that applies to the
country in which you use your Yamaha, please note the following information.
1. The warranty on this model is the same as equivalent models sold in the country where
you will receive service. If you need more information about your warranty coverage or
your Yamaha outside the U.S.A. or Canada, please contact an authorized Yamaha
dealer in your country.
2. Keep a copy of your sales contract or invoice for the purchase of your Yamaha and
present it if you need warranty repairs. This document should show the date of purchase, which is important evidence the repairing dealer will need to be sure your
Yamaha is covered by warranty.

country where you are. He will explain how to get warranty service in that country.
