they can have detrimental effects in marine
engines, because of increased deposits in
the combustion chamber. When enough de-
posits collect, piston rings begin sticking.
Performance drops and engine wear in-
creases dramatically.
While many additives available may reduce
deposits, Yamaha recommends the use of
Ring Free Fuel Additive, available from
your Yamaha dealer. Ring Free Fuel Addi-
tive has repeatedly proven its ability to clean
combustion deposits from inside the engine,
notably the critical piston-ring-land area, and
fuel system components. Follow product la-
beling for use instructions.
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 en-
gine starting and running problems. Yamaha
does not recommend gasohol containing
methanol because it can cause fuel system
