STORAGE
Storing your boat for prolonged
periods of time, such as winter storage,
requires preventative maintenance
to ensure against deterioration. It is
advisable to have the boat serviced
by an authorized Yamaha Boat dealer
before storage. However, the following
procedures can be performed by the
owner with a minimum of tools.
FUEL SYSTEM
Top off the fuel tank with fresh fuel,
adding one ounce of Yamaha Fuel
Conditioner and Stabilizer or an equiv-
alent to each gallon of fuel. A full fuel
tank is less likely to allow condensa-
tion to collect in the tank, reducing the
chance of contaminated fuel. Running
the engines with treated fuel during
cooling system flushing will also help
protect the fuel system.
TIP:
Use ofYamaha Fuel Conditioner and
Stabilizer eliminates the need to drain
the fuel system. Consult your Yamaha
dealer or other qualified mechanic if the
fuel system is to be drained instead.

Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt.
1) Open the cap for the engine you
are going to flush. Press the flush
kit garden hose adapter into the
flush hose connector and turn until
they are securely connected.
2) Start the engine, then immediately
turn on the water supply fully.

could flow back through the
muffler into the crankcase caus-
ing severe engine damage.

diately after starting the engine to
prevent engine overheating.
3) Run the engine at a fast idle for 10
to 15 minutes.
