GASOLINE AND ITS VAPORS ARE HIGH-
LY FLAMMABLE AND EXPLOSIVE!
●
Do not smoke when refueling, and keep

line spills, wipe it up immediately with
dry rags.
●
Do not overfill the fuel tank.
●
Tighten the filler cap securely after re-
fueling.
●
If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline 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.

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 metha-
nol. 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
therefore must not be used in your outboard
motor. All ethanol blends containing more
than 10% ethanol can cause fuel system
damage or engine performance problems.
Yamaha does not recommend gasohol-con-
taining methanol because it can cause fuel
system damage or engine performance
problems.
