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.

●

Incorrect propeller selection and incorrect
use may not only cause engine damage,
but also adversely affect fuel consumption.
Consult your dealer for correct 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

General information

is a good idea to wear a PFD whenever
boating. At a minimum, children and non­swimmers 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.

●

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

2

General information

watch for obstacles and other traffic.

●

Always watch carefully for swimmers dur­ing the engine operation.

●

Stay away from swimming areas.

●

When a swimmer is in the water near you
shift into neutral and shut off the engine.

●

Do not illegally discard empty containers
used to replace or replenish oil. For the
correct processing of empty containers,
consult the dealer where you purchased
the oil.
When replacing oils used to lubricate the

●

product (engine or gear oil), be sure to
wipe away any spilt oil. Never pour oil with­out using a funnel or similar device. If nec­essary, verify the necessary replacement
procedure with the dealer.
Never illegally discard (dump) the product.

●

Yamaha recommends consulting the deal­er on discarding the product.

WARNING

GASOLINE AND ITS VAPORS ARE HIGH­LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep

●

away from sparks, flames, or other
sources of ignition.
Stop engine before refueling.

●

●

Refuel in a well-ventilated area. Refuel
portable fuel tanks off the boat.
Take care not to spill gasoline. If gaso-

●

line spills, wipe it up immediately with
dry rags.
Do not overfill the fuel tank.

●

●

Tighten the filler cap securely after re-

fueling.

●

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
If any gasoline spills onto your skin, im-

●

mediately wash with soap and water.
Change clothing if gasoline spills on it.
Touch the fuel nozzle to the filler open-

●

ing or funnel to help prevent electro­static sparks.

ECM00010

CAUTION:

Use only new clean gasoline which has
been stored in clean containers and is not
contaminated with water or foreign mat­ter.

EMU25580

Gasoline

Recommended gasoline:

Regular unleaded gasoline with a min­imum octane rating of 90 (Research
Octane Number).

EMU25683

Engine oil

Recommended engine oil:

4-stroke motor oil with a combination
of the following SAE and API oil classi­fications

Engine oil type SAE:

10W-30 or 10W-40

Engine oil grade API:

SE, SF, SG, SH, SJ, SL

Engine oil quantity (excluding oil filter):

2.5 L (2.64 US qt) (2.20 Imp.qt)

NOTE:

If the recommended engine oil grades are
not available, select an alternative from the
following chart according to the average
temperatures in your area.

If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.

CAUTION:

All 4-stroke engines are shipped from the
factory without engine oil.

CAUTION:

Do not use a battery that does not meet
the specified capacity. If a battery which

electric system could perform poorly or
be overloaded, causing electric system
damage.

For electric start models, choose a battery
which meets the following specifications.

Battery specifications

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.

Propeller selection

The performance of your outboard motor will

NOTE:

Select a propeller which will allow the engine
to reach the middle or upper half of the oper­ating range at full throttle with the maximum
boat load. If operating conditions such as
light boat loads then allow the engine r/min to
rise above the maximum recommended
range, reduce the throttle setting to maintain
the engine in the proper operating range.

Start-in-gear protection

Yamaha outboard motors affixed with the
pictured label or Yamaha-approved remote
control units are equipped with start-in-gear
protection device(s). This feature permits the
engine to be started only when it is in neutral.

Engine stop lanyard switch

The lock plate must be attached to the en­gine stop switch for the engine to run. The
lanyard 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.

EWM00120

WARNING

Attach the engine stop switch lanyard

●

to a secure place on your clothing, or
your arm or leg while operating.
Do not attach the lanyard to clothing

●

that could tear loose. Do not route the
lanyard where 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.

The engine cannot be started with the lock
plate removed.

“” (down) tilts the outboard motor down
and trims it down. When the switch is re­leased, the outboard motor will stop in its
current position.

EWM01030

WARNING

Use the power trim and tilt switch located
on the bottom engine cowling only when
the boat is at a complete stop with the en­gine off. Attempting to use this 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.

WARNING

An improperly adjusted trim tab could
cause difficult steering. Always test run
after the trim tab has been installed or re­placed to be sure steering is correct. Be
sure you have tightened the bolt after ad­justing the trim tab.

If the boat tends to veer the left (port side),
turn the trim tab rear end to the port side “A”
in the figure. If the boat tends to veer the right
(starboard side), turn the trim tab end to the
starboard side “B” in the figure.
