QSAFETY INFORMATION

8 Before mounting or operating the out-

board 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 out-

board 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 (Petrol) is highly flammable, and

its vapors are flammable and explosive.
Handle and store gasoline (Petrol) care­fully. Make sure there are no gas fumes
or leaking fuel before starting the engine.

1-4

E

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.

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 dur-

ing the engine operation.

8 Stay away from swimming areas.
8 When a swimmer is in the water near you

shift into neutral and shut off the engine.

FUELING INSTRUCTIONS

w

GASOLINE AND ITS VAPORS ARE HIGH­LY FLAMMABLE AND EXPLOSIVE!
8 Do not smoke when refueling, and

keep away from sparks, flames, or
other sources of ignition.

8 Stop engine before refueling.
8 Refuel in a well-ventilated area. Refuel

portable fuel tanks off the boat.

8 Take care not to spill gasoline. If gaso-

line spills, wipe it up immediately with
dry rags.

8 Do not overfill the fuel tank.
8 Tighten the filler cap securely after

refueling.

8 If you should swallow some gasoline

inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

8 If any gasoline spills onto your skin,

immediately wash with soap and
water. Change clothing if gasoline
spills on it.

8 Touch the fuel nozzle to the filler open-

ing or funnel to help prevent electro­static sparks.

cC

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

1-6

E

EMU01799

GASOLINE

Recommended gasoline:

Regular unleaded gasoline

If knocking or pinging occurs, use a differ­ent brand of gasoline or premium unleaded
fuel. If unleaded gasoline is not available,
then premium gasoline can be used.

EMU01356

ENGINE OIL

Recommended engine oil:
YAMALUBE, TWO STROKE MOTOR
OIL FOR MARINE

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
does not meet specifications is used, the
electric system could perform poorly or
be overloaded, causing electric system
damage.

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

EMU01857

Minimum cold cranking amps (CCA/EN):

430 amps at -18°C (-0.4°F)

Minimum rated capacity (20HR/IEC):

70 A·h

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.

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.

E

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.

START-IN-GEAR PROTECTION

Yamaha outboard motors which have the
pictured label 1 affixed to them 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 Neutral. Always select
Neutral before starting the engine.

ENGINE STOP LANYARD SWITCH
(for Tiller control model)

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.

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.
