Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the
engine speed will be limited to about
3,400 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.

Oil level warning lamp
If the oil remaining in the tank drops to
about 1.2 L (0.31 US gal, 0.26 Imp gal) or
the oil filter is clogged, the oil level warning
lamp begins to blink.
If the oil level warning lamp begins to
blink, refill with engine oil as soon as possi-
ble.
NOTE:@
The lamp will light up for 2 seconds after
starting the engine to check the lamp
operation.

If the warning lamp blinks with adequate
oil in the tank, check for a clogged oil fil-
ter.

Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
EJU20550
Gasoline
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 with
the watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow. If tem-
porarily leaving the watercraft with a
full fuel tank, do not leave it in direct
sunlight. Leave it in a well-ventilated
area with the watercraft in a horizontal
position.

Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

Filling the oil tank
WARNING@
Do not add gasoline to the oil tank.
Fire or explosion could result.

Oil in the bilge is a serious fire hazard.
Wipe up any spilled oil immediately.
@
CAUTION:@ Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes
empty the oil injection pump must be
bled to ensure proper oil flow, otherwise
engine damage may occur. If bleeding of
the oil pump is necessary, have a
Yamaha dealer bleed it.
@
1. Open the hood and remove the front stor-
age compartment. Also, remove all seat,
so you can watch the oil level. (See page
2-6 for hood, and pages 2-4 and 2-5 for
seats.)
2. Open the oil tank filler cap, and very
slowly add engine oil to the oil tank.
3. Stop pouring when the oil just reaches
the bottom of the filler tube.
Oil tank capacity:
3.8 L (1.0 US gal, 0.8 Imp gal)

Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove the front seat and front storage com-
partment. (See page 2-5 for front seat, and
2-15 for front storage compartment.) Allow
the engine compartment to remain open for
a few minutes to allow any fuel vapors to
escape. Also, check for loose electrical con-
nections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.

trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.

The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.

Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right
and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Make sure that the jet thrust
nozzle also changes directions as the han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.
