SAFETY

INFORMATION

●

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.

●

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.

●

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.

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.

E

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.’

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

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.

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.

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

Overtaking

If you are passing another vessel, you are
the “Give-Way” vessel. This means that the

1-8

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 rec-
ommended 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.

WARNING

@

NOTE:

@

●

Fuel consumption varies greatly with boat
design, weight, propeller used, engine
trim angle, sea conditions (including
wind), and throttle position. Fuel con­sumption also varies slightly with the type
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.

EMU01412

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.

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.

located on the remote control box.

@

3-12

E

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 out-

●

board 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. Discon-

●

nect 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:

@

Before tilting the motor, follow the pro-

●

cedures under “STOPPING ENGINE”.

Never tilt the motor while the engine is

running. Severe damage from over-

heating can result.

To prevent the cooling water passages

●

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.

longer), several important procedures must
be performed to prevent excessive damage.
It is advisable to have your outboard motor
serviced by an authorized Yamaha dealer
prior to storage. However, the following pro­cedures can be performed by the owner with
a minimum of tools.

CAUTION:

@

To prevent problems which can be

●

caused by oil entering the cylinder
from the sump, keep the outboard
motor upright when transporting and
storing it. If storing or transporting the
outboard motor on its side (not
upright), put it on a cushion after
draining the engine oil.
Store the outboard motor in a dry, well-

●

ventilated place, not in direct sunlight.

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

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.

CHECKING BATTERY
(for Electric start models)

WARNING

@

Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is
poisonous and highly caustic.
Always follow these preventive mea­sures:

Avoid bodily contact with electrolytic

●

fluid as it can cause severe burns or
permanent eye injury.
Wear protective eye gear when han-

●

dling or working near batteries.

Antidote (EXTERNAL):

SKIN - Flush with water.

●

EYES - Flush with water for 15 minutes

●

and get immediate medical attention.

Antidote (INTERNAL):

Drink large quantities of water or milk

●

followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.

Batteries also generate explosive hydro­gen gas; therefore, you should always
follow these preventive measures:

Charge batteries in a well-ventilated

●

area.
Keep batteries away from fire, sparks,

●

or open flames (e.g., welding equip­ment, lighted cigarettes, etc.).
DO NOT SMOKE when charging or

●

handling batteries.
KEEP BATTERIES AND ELECTRO-

●

LYTIC FLUID OUT OF REACH OF CHIL­DREN.

@

4-29

E

CAUTION:

@

A poorly maintained battery will

●

quickly deteriorate.
Ordinary tap-water contains minerals

●

harmful to a battery, and should not be
used for topping-up.

@

1) Check the electrolyte level at least once
a month. Fill to the manufacturer’s rec-
ommended level when necessary. Top
up only with distilled water (or pure de­ionized water suitable to use in batter­ies).

2) Keep the battery always in a good state
of charge. Installing a voltmeter will help
you monitor your battery. If you will not
use the boat for a month or more,
remove the battery from the boat and
store it in a cool, dark place. Completely
recharge the battery before using it.

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
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.

CAUTION:

@

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:

@

●

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.
