Fuel requirements
EMU36771
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. Yamaha re-
comends that you use alcohol-free (see Gas-
ohol) gasoline whenever possible.
ECM01981
● 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
damage. 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. All etha-
nol blends containing more than 10% etha-
nol can cause fuel system damage or cause
engine starting and running problems.
Yamaha does not recommend gasohol con-
taining methanol because it can cause fuel
system damage or engine performance
problems.
EMU36880
Muddy or acidic water
Yamaha strongly recommends that you have
your dealer install the optional chromium-
plated water pump kit if you use the outboard
motor in muddy or acidic water conditions.
However, depending on the model it might
not be required.
EMU36330
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
marine growth.
Do not use anti-fouling paint which includes
copper or graphite. These paints can cause
more rapid engine corrosion.
Recommended gasoline:
Regular unleaded gasoline
