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.

Procedure

Flushing with the flushing attachment
Cooling system flushing is essential to pre-
vent the cooling system from clogging up
with salt, sand, or dirt. In addition, fogging/lu-
bricating of the engine is mandatory to pre-
vent excessive engine damage due to rust.
Perform the flushing and fogging at the same
time.
1. Wash the exterior of the outboard motor
using fresh water. NOTICE: Do not
spray water into the air intake.
[ECM01841]
For further information, see page 79.
2. Fill the fuel tank with fresh fuel and add
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, and then turn on the
water supply. NOTICE: Do not run the
engine without supplying it with cool-
ing 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.
[ECM02001]
TIP:
A flushing attachment is available from your
Yamaha dealer.
5. Run the engine at a fast idle for a few
minutes in neutral while supplying fresh
water. WARNING! Do not touch or re-
move electrical parts when starting or
during operation. Keep hands, hair,
