Fuel System
General Warnings
DANGER!
Gasoline is extremely flammable and highly explosive. Always turn off the engine before refueling. Do not smoke
or allow open flames or sparks near the boat when adding fuel. When filling the gas tank, ground the tank to the
source of gasoline by holding the hose nozzle firmly against the side of the deck filler plate, or ground it in some
other manner. This action prevents static electricity buildup that could cause sparks and ignite fuel vapors.
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, perform all service procedures with the engine turned OFF.
DANGER!
Failure to inspect your work may allow fuel leakage to go undetected. This could become a fire or explosion
hazard.
Gasoline Requirements
Octane
22823
Use unleaded gasoline with the following minimum
octane rating:
● In the U.S.: (R+M)/2 (AKI) - 87
● Outside the U.S.: (RON) - 90
NOTICE! Engine damage resulting from the use of
lower octane gasoline (below 87 AKI or 90 RON) is
considered misuse of the engine and is not covered
by the warranty.
All Volvo Penta gasoline engines are engineered to
operate on AKI 87 (RON 90) octane fuel. Mid-grade
and premium fuels contain injector cleaners and other
additives that protect the fuel system and provide
improved performance. EFI engines may obtain an
increase in power from higher octane fuels.
NOTICE! Leaded gasoline may be available in some
markets. Leaded gasoline will damage the catalysts
and can not be used in engines with catalytic convert-
ers. Catalyst failure due to improper fuel is not covered
by the warranty.
Ethanol-Blended Fuels (E10)
Gasoline is distributed, in the United States and other
markets, containing ethanol. Volvo Penta gasoline
engines may be operated using gasoline blended with
no more than 10% ethanol and that meets the mini-
mum octane specification. 10% ethanol-blended fuel
is also commonly referred to as "E10."
