Post-operation checks
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow water in the bilge to
drain out.
NOTE:@ This watercraft is equipped with an auto-
matic bilge-draining system that removes
water from the engine compartment while
you are underway. However, some residual
water will remain.
@
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See page 4-1 for flushing procedures.)
6. Drain residual water from the exhaust
system by alternately squeezing and
releasing the throttle lever for 10 to
15 seconds while the engine is running.
CAUTION:@ Do not run the engine for more than
15 seconds on land. The engine could
overheat.

Storage
WARNING@ Always place the watercraft upright in a
horizontal position when storing it, oth-
erwise fuel could leak out into the engine
or engine compartment, which could
result in a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU21260
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:@
Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.

Do not run the engine of the watercraft
for more than 15 seconds without sup-
plying water, otherwise the engine may
overheat.

1. Put the watercraft on land in a horizontal
position.
2. Remove the seat. (See page 2-5 for seat
removal and installation procedures.)
3. Remove the flushing hose connector
cap1, and then insert the garden hose
adapter 2 into the flushing hose con-
nector 3 and turn it until it is securely
connected.
4. Connect the garden hose adapter to a
water tap using a hose.
5. Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet nozzle.
6. 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.
7. Turn the water supply off, and then force
the remaining water out from the cooling
passages by alternately squeezing and
releasing the throttle lever for 10 to
15 seconds.
8. Stop the engine.
9. Remove the garden hose adapter and
