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.
EJU33541Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
CAUTION:
ECJ00121

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 without supplying water or
over 4000 r/min on land, otherwise the
engine could overheat.
(1) Remove the watercraft from the water
and place it in a horizontal position.
(2) Remove the seat. (See page 26 for seat
removal and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hoseadapter into the flushing hose connector
and turn it until it is securely connected.
(4) 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.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust 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 of the cooling

stall the flushing hose connector cap.
EJU33620Lubrication
WARNING
EWJ00260
Do not spray flammable rust inhibitor
products on engine surfaces while the en-
gine is hot. The sprayed substance or pro-
pellants could catch fire.
(1) Remove the seat. (See page 26 for seat
removal and installation procedures.)
(2) Loosen the clamp screw and disconnect
the air intake duct.(3) Spray a rust inhibitor into the intake open-
ing for 3 seconds.
(4) Connect the air intake duct and tighten
the clamp screw.
(5) Start the engine in a well-ventilated area
and let it run at idle for 15 seconds.
CAUTION:
ECJ00160
Do not run the engine for more than 15
seconds, otherwise the engine could over-
heat.
(6) Lubricate all cables such as the throttle
and steering cables.
NOTE:
Use a suitable marine grease applicator to
pressure-lubricate the cables and purge out
any moisture between the inner and outer ca-
bles.
(7) Lubricate the areas of the watercraft
specified in “Lubrication points” on page
76.
