Long-term storage

EWJ00331
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 easily by the owner.

Cleaning

(1) Flush the cooling water passages. (See
page 80 for information on flushing the
cooling water passages.)
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 one
ounce of Yamalube Fuel Stabilizer & Condi-
tioner Plus to each gallon of fuel in the fuel
tank before starting the engine.
(2) Clean the watercraft. (See page 81 for in-
formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax
such as Yamalube Professional Polish.
