Transporting and storing out-
board motor
WARNING
EWM02551
● Leaking fuel is a fire hazard. When trans-
porting and storing the outboard motor,
close the fuel cock to prevent fuel from
leaking.
● Never get under the outboard motor
while it is tilted, even when the tilt sup-
port shaft is installed. Severe injury
could occur if the outboard motor acci-
dentally falls.
The outboard motor should be trailered and
stored in the fully tilted-down position. If the
outboard motor cannot be trailered in the fully
tilted-down position, the outboard motor must
be secured in the tilted-up position using a
support device, such as the Yamaha Traile-
ring Support.

Storing outboard motor
When storing your Yamaha outboard motor
for prolonged periods of time (2 months or
longer), several important procedures must
be performed to prevent excessive damage. It
is advisable to have your outboard motor ser-
viced by an authorized Yamaha dealer prior to
storage. However, you, the owner, with a min-
imum of tools, can perform the following pro-
cedures.
NOTICE
ECM02281
Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.

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.
T
IP:
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 ex-
pansion with temperature changes.
Do not cap the fuel tank vent. Excessive pres-
sure 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 move-
ment which can bring in water through con-
densation as the air temperature changes.
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.
