Gasoline
Use a good quality gasoline that meets the
minimum octane rating. If knocking or ping-
ing occurs, use a different brand of gasoline
or premium unleaded fuel.
Recommended fuel:
F200CET Regular unleaded gasoline
F225BET Regular unleaded gasoline
F225CET Premium unleaded gasoline
FL200CET Regular unleaded gasoline
FL225BET Regular unleaded gasoline
Min. research octane number (RON):

NOTICE
Do not use leaded gasoline. Leaded
gasoline can seriously damage the en-
gine.
Avoid getting water and contaminants in
the fuel tank. Contaminated fuel can
cause poor performance or engine dam-
age. Use only fresh gasoline that has
been stored in clean containers.

Gasohol
There are two types of gasohol: gasohol con-
API
taining ethanol (E10) and that containing
methanol. Ethanol can be used if the ethanol
content does not exceed 10% and the fuel
meets the minimum octane ratings. E85 is a
SH
SJ
fuel containing 85% ethanol and must not be
SL
used in your outboard motor. All ethanol
blends containing more than 10% ethanol
can cause fuel system damage or cause en-
gine starting and running problems. Yamaha
does not recommend gasohol containing
methanol because it can cause fuel system
damage or engine performance problems.
It is recommended that you install a water-
separating marine fuel filter assembly (10 mi-
cron minimum) between your boat's fuel tank
and outboard motor when using ethanol. Eth-
anol is known to allow moisture to be ab-
sorbed into boat fuel tanks and systems.
Moisture in the fuel can cause corrosion of
metallic fuel system components, starting
and running complaints and require addition-
al fuel system maintenance.
EMU36331
Anti-fouling paint
A clean hull improves boat performance. The
boat bottom should be kept as clean of ma-
rine growth as possible. If necessary, the
boat bottom can be coated with an anti-foul-
ing paint approved for your area to inhibit ma-
rine growth.
Do not use anti-fouling paint which includes
copper or graphite. These paints can cause
more rapid engine corrosion.
