5-2 Indmar Marine Engines
Frequently inspect fuel lines and connec-
tions for leaks or deterioration.
Indmar recommends the regular use of Marine Formula
Sta-Bil fuel stabilizer for boat users that consume less
than a tank of fuel every two weeks. Today’s fuels are
more susceptible to degradation and the use of a quality
stabilizer will help ensure fewer problems for the occa-
sional boater.
If your boat has not been used for more than 30 days
with fuel in the tank (even stabilized fuel), the engine
may run poorly until the “old” fuel is used up. Indmar will
not pay for repairs to carburetors or fuel injection compo-
nents that are inoperable or damaged from old and/or
poor quality fuel.
USING OXYGENATED FUELS OR FUELS WITH
ALCOHOL
MBTE (methyl butyl tertiary ether) is an oxygenate and
octane enhancer. This compound may be blended with
fuel. Fuel that is no more than 15% MBTE is acceptable
for use in your Indmar engine.
Ethyl alcohol, ethanol or grain alcohol is acceptable as
long as it is a blend and the blended fuel contains no
more than 10% ethanol.
Fuels that are blended to contain methanol
or wood alcohol should not be used in
Indmar engines. These fuels can corrode
metal parts in your fuel system and engine.
Fuels that contain methanol will damage
your engine. Damage caused by the use of
fuels that contain methanol is not covered by
your warranty.
FUELS IN OTHER COUNTRIES
If you operate your Indmar engine outside the USA or
Canada, unleaded fuels may be difficult to obtain.
Leaded fuels must not be used in engines with catalytic
converters or serious damage will occur.
