Safety information
EMU33622
Outboard motor safety
Observe these precautions at all times.
EMU36501
Propeller
People can be injured or killed if they come
in contact with the propeller. The propeller
can keep moving even when the motor is in
neutral, and sharp edges of the propeller can
cut even when stationary.
● Stop the engine when a person is in the
water near you.
● Keep people out of reach of the propeller,
even when the engine is off.
EMU33630
Rotating parts
Hands, feet, hair, jewelry, clothing, PFD
straps, etc. can become entangled with internal rotating parts of the engine, resulting in
serious injury or death.
Keep the top cowling in place whenever possible. Do not remove or replace the cowling
with the engine running.
Only operate the engine with the cowling removed according to the specific instructions
in the manual. Keep hands, feet, hair, jewelry, clothing, PFD straps, etc. away from any
exposed moving parts.
EMU33640
Hot parts
During and after operation, engine parts are
hot enough to cause burns. Avoid touching
any parts under the top cowling until the engine has cooled.
EMU33650
Electric shock
Do not touch any electrical parts while starting or operating the engine. They can cause
shock or electrocution.
EMU33660
Power trim and tilt
Body parts can be crushed between the mo-
tor and the clamp bracket when the motor is
trimmed or tilted. Keep body parts out of this
area at all times. Be sure no one is in this
area before operating the power trim and tilt
mechanism.
The power trim and tilt switches operate
even when the main switch is off. Keep people be away from the switches whenever
working around the motor.
Never get under the lower unit while it is tilted, even when the tilt support lever is locked.
Severe injury could occur if the outboard motor accidentally falls.
EMU33671
Engine shut-off cord (lanyard)
Attach the engine shut-off cord so that the
engine stops if the operator falls overboard
or leaves the helm. This prevents the boat
from running away under power and leaving
people stranded, or running over people or
objects.
Always attach the engine shut-off cord to a
secure place on your clothing or your arm or
leg while operating. Do not remove it to leave
the helm while the boat is moving. Do not attach the cord to clothing that could tear
loose, or route the cord where it could become entangled, preventing it from functioning.
Do not route the cord where it is likely to be
accidentally pulled out. If the cord is pulled
during operation, the engine will shut off and
you will lose most steering control. The boat
could slow rapidly, throwing people and objects forward.
EMU33810
Gasoline
Gasoline and its vapors are highly flammable and explosive. Always, refuel according to the procedure on page 56 to
reduce the risk of fire and explosion.

6C1-9-19.book 2 ページ 2010年2月17日 水曜日 午後1時38分
Safety information
EMU33820
Gasoline exposure and spills
Take care not to spill gasoline. If gasoline
spills, wipe it up immediately with dry rags.
Dispose of rags properly.
If any gasoline spills onto your skin, immediately wash with soap and water. Change
clothing if gasoline spills on it.
If you swallow gasoline, inhale a lot of gasoline vapor, or get gasoline in your eyes, get
immediate medical attention. Never siphon
fuel by mouth.
EMU33900
Carbon monoxide
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.
EMU33780
Modifications
Do not attempt to modify this outboard motor. Modifications to your outboard motor
may reduce safety and reliability, and render
the outboard unsafe or illegal to use.
EMU33740
Boating safety
This section includes a few of the many important safety precautions that you should
follow when boating.
EMU33710
Alcohol and drugs
Never operate after drinking alcohol or taking
drugs. Intoxication is one of the most common factors contributing to boating fatalities.
EMU33720
Personal flotation devices
Have an approved personal flotation device
(PFD) on board for every occupant. Yamaha
recommends that you must wear a PFD
2
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.
EMU33731
People in the water
Always watch carefully for people in the water, such as swimmers, skiers, or divers,
whenever the engine is running. When
someone is in the water near the boat, shift
into neutral and stop the engine.
Stay away from swimming areas. Swimmers
can be hard to see.
The propeller can keep moving even when
the motor is in neutral. Stop the engine when
a person is in the water near you.
EMU33751
Passengers
Consult your boat manufacturer’s instructions for details about appropriate passenger
locations in your boat and be sure all passengers are positioned properly before accelerating and when operating above an idle
speed. Standing or sitting in non-designated
locations may result in being thrown either
overboard or within the boat due to waves,
wakes, or sudden changes in speed or direction. Even when people are positioned properly, alert your passengers if you must make
any unusual maneuver. Always avoid jumping waves or wakes.
EMU33760
Overloading
Do not overload the boat. Consult the boat
capacity plate or boat manufacturer for maximum weight and number of passengers. Be
sure that weight is properly distributed according to the boat manufacturers instructions. Overloading or incorrect weight
distribution can compromise the boats handling and lead to an accident, capsizing or
6C1-9-19.book 3 ページ 2010年2月17日 水曜日 午後1時38分
Safety information
swamping.
EMU33800
Accident reporting
EMU33772
Avoid collisions
Scan constantly for people, objects, and other boats. Be alert for conditions that limit your
visibility or block your vision of others.
ZMU06025
Operate defensively at safe speeds and
keep a safe distance away from people, objects, and other boats.
● Do not follow directly behind other boats or
waterskiers.
● Avoid sharp turns or other maneuvers that
make it hard for others to avoid you or understand where you are going.
● Avoid areas with submerged objects or
shallow water.
● Ride within your limits and avoid aggressive maneuvers to reduce the risk of loss
of control, ejection, and collision.
● Take early action to avoid collisions. Remember, boats do not have brakes, and
stopping the engine or reducing throttle
can reduce the ability to steer. If you are
not sure that you can stop in time before
hitting an obstacle, apply throttle and turn
in another direction.
EMU33790
Weather
Stay informed about the weather. Check
weather forecasts before boating. Avoid
boating in hazardous weather.
Boat operators are required by law to file a
Boating Accident Report with their state
boating law enforcement agency if their boat
is involved in any of the following accidents:
1. There is loss of life or probable loss of
life.
2. There is personal injury that requires
medical attention beyond first aid.
3. There is property damage to boats or
other property over a certain amount.
4. There is complete loss of a boat.
Contact local law enforcement personnel if a
report is necessary.
EMU33870
Boat education and training
Operators should take a boating safety
course. This may be required in your state.
Many of the organizations listed in the next
section can provide information about courses in your area.
You may also want to consider an Internetbased program for basic boater education.
The Online Boating Safety Course provided
by the BoatU.S. Foundation, is approved by
the National Association of State Boating
Law Administrators (NASBLA) and recognized by the United States Coast Guard.
Most, but not all, states accept this course to
meet their minimum requirements. While it
cannot replace an in-depth course such as
one offered by the U.S. Coast Guard, U.S.
Power Squadron, or other organization, this
online course does provide a general overview of the basics in boating safety, requirements, navigation, and operation. Upon
successful completion of the course, the
user can download a certificate of completion immediately or, for a small charge, request one by mail. To take this free course,
go to boatus.org.

Passenger training
Make sure at least one other passenger is
trained to operate the boat in the event of an
emergency.
EMU33890
Boating safety publications
Be informed about boating safety. Additional
publications and information can be obtained
from many boating organizations.
EMU33590
Laws and regulations
Know the marine laws and regulations where
you will be boating- and obey them. Several
sets of rules prevail according to geographic
location, but all are basically the same as the
International Rules of the Road. The rules
presented in the following section are condensed- and have been provided for your
convenience only.
Contact the U.S. Coast Guard, the National
Association of State Boating Law Administrators, or your local Power Squadron for a
complete set of rules governing the waters in
which you will be using your boat.

Basic boating rules (Rules of
the road)
Just as there are rules that apply when you
are driving on streets and highways, there
are waterway rules that apply when you are
driving your boat. These rules are used internationally. (For U.S.A.: 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.
EMU33700
Steering and sailing rules and sound
signals
Whenever two vessels on the water meet
one another, one vessel has the right-of-
6C1-9-19.book 5 ページ 2010年2月17日 水曜日 午後1時38分
Safety information
way; it is called the “stand-on” vessel. The
vessel that 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.
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 that 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.
EMU25521
Rules when encountering vessels
There are three main situations that 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 GiveWay 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 right-ofway 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.
5
6C1-9-19.book 6 ページ 2010年2月17日 水曜日 午後1時38分
Safety information
EMU25531
Other special situations
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
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.
6
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 that 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 power-driven
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 that can navigate
only in such a channel.
6C1-9-19.book 7 ページ 2010年2月17日 水曜日 午後1時38分
Safety information
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.

EMU34194
Propeller selection
Next to selecting an outboard motor, selecting the right propeller is one of the most important purchasing decisions a boater can
make. The type, size, and design of your propeller have a direct impact on acceleration,
top speed, fuel economy, and even engine
life. Yamaha designs and manufactures propellers for every Yamaha outboard motor
and every application.
Your outboard motor came with a Yamaha
propeller selected to perform well over a
range of applications, but there may be uses
where a different propeller would be more
appropriate.
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the middle or upper half of the operating
range at full throttle with the maximum boatload. Generally, select a larger pitch propeller for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, select the propeller
that lets the engine run in the proper range
for your maximum load but remember that
you may need to reduce your throttle setting
to stay within the recommended engine
speed range when carrying lighter loads.
To check the propeller, see page 85.

If the recommended engine oil grades are
not available, select an alternative from the
following chart according to the average temperatures in your area.
Gasoline
Use a good quality gasoline that meets the
minimum octane rating. If knocking or pinging occurs, use a different brand of gasoline
or premium unleaded fuel. Yamaha recomends that you use alcohol-free (see Gasohol) gasoline whenever possible.
Recommended gasoline:
Regular unleaded gasoline with a minimum Octane rating of 86 (Pump Octane Number) = (R+M)/2
ECM01981
NOTICE
●
●
Do not use leaded gasoline. Leaded
gasoline can seriously damage the engine.
Avoid getting water and contaminants
in the fuel tank. Contaminated fuel can
cause poor performance or engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol containing ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. E85 is a
fuel containing 85% ethanol and must not be
used in your outboard motor. All ethanol
blends containing more than 10% ethanol
can cause fuel system damage or cause engine starting and running problems. Yamaha
does not recommend gasohol containing
methanol because it can cause fuel system
damage or engine performance problems.
It is recommended that you install a waterseparating marine fuel filter assembly (10 mi-

rine growth 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.
EMU27270
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 Fuel Additive has repeatedly proven its ability to clean
combustion deposits from inside the engine,
notably the critical piston-ring-land area, and
fuel system components. Follow product labeling for use instructions.

Keep the following items onboard in case
there is trouble with the outboard motor.
● A tool kit with assorted screwdrivers, pliers, wrenches (including metric sizes), and

Throttle friction adjuster
A friction device provides adjustable resistance to movement of the throttle grip or the
remote control lever, and can be set according to operator preference.
To increase resistance, turn the adjuster
clockwise. To decrease resistance, turn the
adjuster counterclockwise. WARNING! Do
not overtighten the friction adjuster. If
there is too much resistance, it could be
difficult to move the remote control lever
or throttle grip, which could result in an
accident. [EWM00032]

Engine shut-off cord (lanyard) and
clip
The clip must be attached to the engine shutoff switch for the engine to run. The cord
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
cord will pull out the clip, stopping ignition to
the engine. This will prevent the boat from
running away under power. WARNING! Attach the engine shut-off cord to a secure
place on your clothing, or your arm or leg
while operating. Do not attach the cord to
clothing that could tear loose. Do not
route the cord where it could become entangled, preventing it from functioning.
Avoid accidentally pulling the cord 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. [EWM00122]

Installation
The information presented in this section is
intended as reference only. It is not possible
to provide complete instructions for every
possible boat and motor combination. Proper
mounting depends in part on experience and
the specific boat and motor combination.
EWM01590

WARNING
●
●
Overpowering a boat could 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.
Improper mounting of the outboard motor could result in hazardous conditions such as poor handling, loss of
control, or fire hazards. For permanently mounted models, your dealer or other person experienced in proper rigging
should mount the motor.
EMU33470
Mounting the outboard motor
The outboard motor should be mounted so
that the boat is well balanced. Otherwise, the
boat could be hard to steer. For single-engine boats, mount the outboard motor on the
centerline (keel line) of the boat.
ZMU01760
1. Center line (keel line)
EMU26933
Mounting height (boat bottom)
The mounting height of your outboard motor
affects its efficiency and reliability. If it is
mounted too high, propeller ventilation may
occur, which will reduce propulsion due to
excessive propeller slip, and the water intakes for the cooling system may not get adequate water supply, which can cause
engine overheating. If the engine is mounted
too low, water resistance (drag) will increase,
thereby reducing engine efficiency and performance.
Most commonly, outboard motor should be
mounted so that the anti-cavitation plate is in
alignment with the bottom of the boat. The
optimum mounting height of the outboard
motor is affected by the boat/motor combination and the desired use. Test runs at different heights can help determine the optimum
mounting height. Consult your Yamaha dealer or boat manufacturer for further information on determining the proper mounting
height.

NOTICE
●
●
Make sure that the idle hole is high
enough to prevent water from entering
the engine even if the boat is stationary
with the maximum load.
Incorrect engine height or obstructions
to the smooth flow of water (such as the
design or condition of the boat, or accessories, such as transom ladders or
depth finder transducers) can create
airborne water spray while the boat is
cruising. If the outboard motor is operated continuously in the presence of
airborne water spray, enough water
could enter the engine through the air
intake opening in the top cowling to
cause severe engine damage. Remove
the cause of the airborne water spray.

Fill engine oil
The engine is shipped from the factory without engine oil. If your dealer did not fill the oil,
you must fill it before starting the engine.
NOTICE: Check that the engine is filled
with oil before first-time operation to
avoid severe engine damage. [ECM01781]
The engine is shipped with the following
sticker, which should be removed after engine oil is filled for the first time. For more information on checking the engine oil level,
see page 53.
For 10 hours for breaking in engine avoid extended idling, rough water and crowded areas.
1. For the first hour of operation:
Run the engine at varying speeds up to
2000 r/min or approximately half throttle.
2. For the second hour of operation:
Increase engine speed as much as necessary to put the boat on plane (but
avoid full-throttle operation), then back
off on the throttle while keeping the boat
at a planing speed.
3. Remaining 8 hours:
Run the engine at any speed. However,
avoid operating at full throttle for more
than 5 minutes at a time.
4. After the first 10 hours:
Operate the engine normally.

Your new engine requires a period of breakin to allow mating surfaces of moving parts to
wear in evenly. Correct break-in will help ensure proper performance and longer engine
life. NOTICE: Failure to follow the break-in
procedure could result in reduced engine
life or even severe engine damage. [ECM00801]
If any item in “Checks before starting engine” is not working properly, have it inspected and repaired before operating
the outboard motor. Otherwise, an accident could occur.

Tighten the air vent screw on the fuel
tank cap (if equipped).
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.
The trim angle of the outboard motor helps
determine the position of the bow of the boat
in the water. Correct trim angle will help improve performance and fuel economy while
reducing strain on the engine. 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.

Make test runs with the trim set to different
angles to find the position that works best for
your boat and operating conditions.
EMU27912
Adjusting boat trim
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. With the
bow up, the boat may have a greater tendency to steer to one side or the other. Compensate for this as you steer. When the bow of
the boat is down, it is easier to accelerate
from a standing start onto plane.
Bow Up
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-out can also cause
the propeller to ventilate, which reduces performance further, and the boat may “porpoise” (hop in the water), which could throw
the operator and passengers overboard.
66
Bow Down
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.
TIP:
Depending on the type of boat, the outboard
motor trim angle may have little effect on the
trim of the boat when operating.
EMU27935
Tilting up and down
If the engine will be stopped for some time or
if the boat is moored in shallows, the outboard motor should be tilted up to protect the
propeller and lower casing from damage by
collision with obstructions, and also to reduce salt corrosion.

WARNING
These procedures require mechanical
skills, tools, and supplies. If you do not
have the proper skills, tools, or supplies
to perform a maintenance procedure,
have a Yamaha dealer or other qualified
mechanic do the work.
The procedures involve disassembling
the motor and exposing dangerous parts.
To reduce the risk of injury from moving,
hot, or electrical parts:
● Turn off the engine and keep the key(s)
and engine shut-off cord (lanyard) with
you when you perform maintenance unless otherwise specified.
● The power trim and tilt switches operate even when the ignition key is off.
Keep people away from the switches
whenever working around the motor.
When the motor is tilted, keep away
from the area under it or between it and
the clamp bracket. Be sure no one is in
this area before operating the power
trim and tilt mechanism.
● Allow the engine to cool before handling hot parts or fluids.
● Always completely reassemble the motor before operation.
Maintenance, replacement, or repair of
the emission control devices and systems may be performed by any marine
engine repair establishment or individual.
All warranty repairs, however, including
those to the emission control system,
must be performed by an authorized

Maintenance interval guidelines
The service intervals provided in the Maintenance Chart were developed based upon
“typical” use that includes operating at varied
speeds, with sufficient time for engine warm
up and cool-down, a medium to light load,
and an average cruising speed near the
3000 to 4000 rpm range. As with any engine,
however, if your normal operating conditions
are different, you should consider service
more often than shown, especially how often
you change your engine oil and gear oil. Examples might include extended wide-openthrottle use or long periods of trolling or
idling, carrying heavy loads, or frequent
starting and stopping or shifting. More frequent maintenance will often pay off many
times over in increased engine life and greater owner satisfaction. Consult your Yamaha
dealer for additional maintenance recommendations.

Cleaning and adjusting spark plug
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.
1. Remove the spark plug caps from the
spark plugs.
2. Remove the spark plug. If electrode erosion becomes excessive, or if carbon

Starter will not operate
If the starter mechanism does not operate
(the engine cannot be cranked with the starter), the engine can be started manually with
an emergency starter rope. However, the engine cannot be started manually if the battery
voltage is low. If the battery is discharged to
9 volts or below, the electric fuel pump will
not operate.

WARNING
●
●
●
Use this procedure only in an emergency to return to the nearest port for repairs.
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.
Attach the engine shut-off cord to a se-
100
cure place on your clothing, or your
arm or leg while operating the boat.
Do not attach the cord to clothing that
could tear loose. Do not route the cord
where it could become entangled, preventing it from functioning.
Avoid accidentally pulling the cord 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.
Make sure no one is standing behind
you when pulling the starter rope. It
could whip behind you and injure
someone.
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.
Do not touch the ignition coil, spark
plug wire, spark plug cap, or other electrical components when starting or operating the motor. You could get an
electrical shock.
