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.
NOTE:
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.
(7) Stop the engine.
(8) Remove the garden hose adapter and in-
stall the flushing hose connector cap.

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.

EJU34371Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
The spark plug is an important engine compo-
nent 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 di-
agnose any problems yourself. Have a
Yamaha dealer service the watercraft.
Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon Difference of A and B:
