Transporting and storing
outboard motor
WARNING
EWM04280
Leaking fuel is a fire hazard. When
transporting and storing the outboard
motor, close the fuel tank selector valve
to prevent fuel from leaking.
Never get under the outboard motor
while it is tilted, even when the tilt sup-
port shaft is installed or the tilt support
lever is locked. Severe injury could oc-
cur if the outboard motor accidentally
falls.
The outboard motor should be trailered and
stored in the fully tilted-down position. If the
outboard motor cannot be trailered in the ful-
ly tilted-down position, the outboard motor
must be secured in the tilted-up position us-
ing a support device, such as the Yamaha
Trailering Support.
EMU41002
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
serviced by an authorized Yamaha dealer
prior to storage. However, you, the owner,
with a minimum of tools, can perform the fol-
lowing procedures.
NOTICE
ECM02282
Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.
EMU41382
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 pro-
vide 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 recommend-
ed. 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.
