Fueling instructions
WARNING
EWM00010
GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
● Do not smoke when refueling, and keep
away from sparks, flames, or other
sources of ignition.
● Stop engine before refueling.
●
Refuel in a well-ventilated area. Refuel
portable fuel tanks off the boat.
● Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags.
● Do not overfill the fuel tank.
●
Tighten the filler cap securely after refu-
eling.
● If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.
●
If any gasoline spills onto your skin, im-
mediately wash with soap and water.
Change clothing if gasoline spills on it.
●
Touch the fuel nozzle to the filler open-
ing or funnel to help prevent electrostat-

EMU33960
Gasoline
If knocking or pinging occurs, use a different
brand of gasoline or premium unleaded fuel.
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets minimum octane ratings. E-85 is a
fuel blend containing 85% ethanol and there-
fore must not be used in your outboard motor.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems. Yamaha does
not recommend gasohol-containing methanol
because it can cause fuel system damage or
engine performance problems.
