search Octane Number).
ECM01981
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 or engine dam-
age. Use only fresh gasoline that has
been stored in clean containers.
Gasohol
There are two types of gasohol: gasohol con-
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
fuel containing 85% ethanol and must not be
used in your outboard motor. All ethanol
blends containing more than 10% ethanol can
cause fuel system damage or cause engine
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 additional fuel
system maintenance.
Specifications and requirements
EMU36880
Yamaha strongly recommends that you have
your dealer install the optional chromium-plat-
ed water pump kit if you use the outboard mo-
tor in muddy or acidic water conditions.
However, depending on the model it might not
be required.
EMU36330
A clean hull improves boat performance. The
boat bottom should be kept as clean of marine
growth as possible. If necessary, the boat bot-
tom can be coated with an anti-fouling paint
approved for your area to inhibit marine
growth.
Do not use anti-fouling paint which includes
copper or graphite. These paints can cause
more rapid engine corrosion.
