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.
EJU37570Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the rear seat and watertight
compartment. (See page 24 for seat re-
moval and installation procedures.)
(3) 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.(4) Connect the garden hose adapter to a
water tap using a garden hose.
TIP:
A garden hose is not included.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust nozzle.
NOTICE: Do not run the engine for
more than 15 seconds without supply-
ing water or over 4000 r/min on land,
otherwise the engine could overheat.
[ECJ01050]
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(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. NOTICE: Do not sup-
ply water to the cooling water passag-
es when the engine is not running. The
water could flow back through the
muffler into the engine, causing se-
vere engine damage.
[ECJ00122]
(7) Turn the water supply off, and then force
the remaining water out of the cooling
