WARNING
Always place the watercraft upright in a horizontal position when storing it, otherwise fuel could leak out into the engine or engine compartment, which could create a fire hazard.
Storage for long periods of time, such as winter 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.
(1)Place the watercraft in a horizontal posi- tion.
(2)Remove the rear seat and watertight compartment. (See page 28 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.

If you will be storing the watercraft for a prolonged period, such as winter storage, top off the fuel tank with fresh gasoline and add one ounce of Yamaha Fuel Stabilizer and Conditioner to each gallon of fuel in the fuel tank before starting the engine.
