Gasoline Containing Alcohol

Many brands of gasoline being sold today contain al-
cohol. Two commonly used alcohol additives are Eth-
anol (ethyl alcohol) and Methanol (CH
called methyl alcohol.
See your boat owner's manual to see if the boat's fuel
system is compatible with alcohol blended fuels. If it is,
your engine may be operated using gasoline blended
with no more than 10% Ethanol meeting the minimum
octane specification.
If you use gasoline that contains ethanol, be aware of
the following:
•
The engine will operate leaner with ethanol
blended fuel. This may cause engine problems
such as vapor lock, low speed stall, or hard start-
ing.
•
Ethanol blended fuels attract and hold moisture.
Moisture inside fuel tanks can cause corrosion
of the tank material. Inspect fuel tanks at least
annually. Replace fuel tanks if inspection indi-
cates leakage or corrosion.

Leaded Fuels

EFI models: Some marinas sell fuel with lead addi-
tives. Do not use leaded fuel, as it may block the fuel
injectors and cause leakage.
DANGER! Fuel leakage can contribute to a
fire and/or explosion. Frequently inspect non-
metallic parts of the engine's fuel system and
replace if excessive stiffness, deterioration,
or fuel leakage is found.
DANGER! To prevent fire and explosion, per-
form all service procedures with the engine
turned OFF.
DANGER! Failure to inspect your work may al-
low fuel leakage to go undetected. This could
become a fire or explosion hazard.
After completing service procedures, start engine and
check entire fuel system for possible leaks.
To prevent fire and explosion, Volvo Penta fuel system
components meet U.S. Coast Guard requirements for
fuel and fuel vapor containment. Do not substitute au-
tomotive or other non-approved parts.
