Storage
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage. However, the following
procedures can be performed by the owner.
EJU33520Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
WARNING
EWJ00270
Do not start the engine on land if anyone is
behind the watercraft. Hot water and
steam spurting from the exhaust outlet
into the air can cause serious burns.
CAUTION:
ECJ00130

Do not supply water to the cooling water
passages when the engine is not run-
ning. The water could flow back through
the muffler into the crankcase, causing
severe engine damage.

Do not run the engine for more than 15
seconds on land without supplying wa-
ter, otherwise the engine could over-
heat.

Do not run the engine over 4000 r/min on
land, otherwise the catalytic converter
could be seriously damaged.
(1) Remove the watercraft from the water
and place it in a horizontal position.(2) Remove the flushing hose connector
cap, and then insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.
(3) Connect the garden hose adapter to a
water tap using a garden hose.

A garden hose is not included and must be
purchased separately.
(4) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the cooling water pi-
lot outlet.
(5) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and repeat
the above steps.
(6) Turn the water supply off, and then force
the remaining water out of the cooling
water passages by running the engine at
4000 r/min or less for 10 to 15 seconds.

EJU33651Fuel system
WARNING
EWJ00290
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!

Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.

Stop the 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 tempo-
rarily leaving the watercraft with a full
fuel tank, do not leave it in direct sun-
light. Leave it in a well-ventilated area
with the watercraft in a horizontal posi-
tion.

Tighten the fuel tank filler cap securely
after refueling.

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

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
Top off the fuel tank with fresh gasoline and
add 470 ml (15.9 US oz, 16.5 Imp oz) of
Yamaha Fuel Stabilizer and Conditioner.
CAUTION:
ECJ00140
Use only Yamaha Fuel Stabilizer and Con-
ditioner, otherwise the catalytic converter
could be seriously damaged.
EJU33680Battery
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft and store it in a cool, dry place.

and other deposits are excessive, replace the
spark plug with the specified plug.
Measure the spark plug gap with a wire thick-
ness gauge. Replace the spark plugs or ad-
just the gap to specification if necessary.
To install a spark plug:
(1) Clean the gasket surface.
(2) Wipe any dirt from the threads of the
spark plug.
(3) Install the spark plug, and then tighten it
to the specified torque.
(4) Install the spark plug cap.
NOTE:

Wipe off any water on the spark plug or in-
side the spark plug cap before installing the
cap. Push the spark plug cap down until it is
securely installed.

If a torque wrench is not available when you
are installing a spark plug, a good estimate
of the correct torque is 1/4 turn to 1/2 turnpast finger tight using the spark plug
wrench included in the tool kit. Have the
spark plug adjusted to the correct torque
with a torque wrench as soon as possible.
