Using Oxygenated Fuels Or Fuels With Alcohol - Indmar 5.7L Vortec Operator's Manual

Figure 5.2 – Inspecting Fuel Lines
5-2
Frequently inspect fuel lines and connec-
tions for leaks or deterioration.
Indmar recommends the regular use of Sta-Bil fuel stabi-
lizer 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 occasional 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.
