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.

Flushing 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:

●
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.

turn the water supply on until water flows
out continually from the cooling water pi-
lot outlet.

3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and repeat
the above steps.

water passages by running the engine at
4000 r/min or less for 10 to 15 seconds.
