have detrimental effects in marine engines,
because of increased deposits in the combus-
tion chamber. When enough deposits collect,
piston rings begin sticking. Performance
drops and engine wear increases dramatical-
ly.
While many additives available may reduce
deposits, Yamaha recommends the use of
Ring Free Fuel Additive, available from your
Yamaha dealer. Ring Free Fuel Additive
has repeatedly proven its ability to clean com-
bustion deposits from inside the engine, nota-
bly the critical piston-ring-land area, and fuel
system components. Follow product labeling
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
for use instructions.

Anti-fouling paint
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
system maintenance.
