Fuel

EWJ00282
WARNING
Gasoline and gasoline vapors are ex-
G
tremely flammable. To avoid fires and
explosions and to reduce the risk of in-
jury when refueling, follow these in-
structions.
Gasoline is poisonous and can cause in-
G
jury or death. Handle gasoline with care.
Never siphon gasoline by mouth. If you
should swallow some gasoline, inhale a
lot of gasoline vapor, or get some gaso-
line in your eyes, see your doctor imme-
diately. If gasoline spills on your skin,
wash with soap and water. If gasoline
spills on your clothing, change your
clothes.
ECJ00321
NOTICE
Do not use leaded gasoline. Leaded gas-
G
oline can seriously damage the engine.
Avoid getting water and contaminants in
G
the fuel tank. Contaminated fuel can
cause poor performance and engine
damage. Use only fresh gasoline that
has been stored in clean containers.
Recommended fuel:
Regular unleaded gasoline with a
minimum octane rating of
86
(Pump octane number) = (R + M)/2
90 (Research octane number)
Gasohol
There are two types of gasohol: gasohol con-
taining ethanol and that containing methanol.
27
Gasohol containing ethanol can be used if
ethanol content does not exceed 10% and the
fuel meets the minimum octane ratings. E-85
is a fuel blend containing 85% ethanol and
therefore must not be used in this watercraft.
All ethanol blends containing more than 10%
ethanol can cause fuel system damage or en-
gine performance problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage and engine performance
problems.

YAMALUBE 2-W or TC-W3 outboard
