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 me-
chanic if the fuel system is to be drained
instead.
