STORAGE
Storing your boat for prolonged peri-
ods of time, such as winter storage,
requires preventative maintenance to
ensure against deterioration. It is advis-
able to have the boat serviced by an
authorized Yamaha Boat dealer before
storage. However, the following proce-
dures can be performed by the owner
with a minimum of tools.
FUEL SYSTEM
Fill the fuel tank with fresh fuel, adding
one ounce of Yamaha Fuel Conditioner
and Stabilizer or an equivalent to each
gallon of fuel. Do not “top off” the tank,
because fuel could spill. 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
Flush Hose Connector
Garden Hose Adapter
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.
•
Never turn on the water before
starting the engine. The water
could flow back through the muf-
fler into the crankcase causing
severe engine damage.
•
Be sure to turn on the water imme-
diately after starting the engine to
prevent engine overheating.
3) Run the engine at a fast idle for 10
to 15 minutes.
