Conditioning and stabilizing gasoline
When preparing to store a boat for extended
periods (2 months or longer) it is best to com-
pletely remove all gasoline from the boat's
fuel tank(s). If it is not possible to remove the
gasoline, add one ounce of "Yamalube Fuel
Stabilizer & Conditioner Plus" to each gallon
of gasoline in a full tank of gasoline to provide
fuel stability and corrosion protection.
TIP:
Do not fill the fuel tank(s) to the point of over-
flowing. Approximately 7/8 full will allow
enough space in the fuel tank to prevent gas-
oline purging from the fuel tank vent due to
expansion with temperature changes.
Do not cap the fuel tank vent. Excessive
pressure could damage the boat and motor's
fuel systems.
A partially filled fuel tank, less than 7/8 full but
not completely empty, is not recommended.
Air space above the gasoline allows air
movement which can bring in water through
condensation as the air temperature chang-
es.
Condensation inside the fuel tank can cause
corrosion problems and phase separation of
gasoline containing ethanol.

Consult your Yamaha dealer concerning pre-
ventative measures that may work best for
the gasoline and environmental conditions in
your area.

one ounce of "Yamalube Fuel Stabilizer
& Conditioner Plus" to each gallon of fu-
el.
TIP:
The use of "Yamalube Fuel Stabilizer & Con-
ditioner Plus" 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.
3.
Remove the top cowling and propeller.
4.
Install the flushing attachment over the
cooling water inlet. NOTICE: Do not run
the engine without supplying it with
cooling water. Either the engine water
pump will be damaged or the engine
will be damaged from overheating.
Before starting the engine, be sure to
supply water to the cooling water pas-
sages. Avoid running the outboard
motor at high speed while on the
flushing attachment, otherwise over-
heating could occur.
