Fuel Requirements
Minimum Octane
Evinrude/Johnson outboards are certified to oper-
ate on unleaded automotive gasoline with an
octane rating equal to or higher than:
•
87 (R+M)/2 AKI, or
•
90 RON
Use unleaded gasoline that contains methyl ter-
tiary butyl ether (MTBE)
ONLY if the MTBE con-
tent does not exceed 15% by volume.
Use alcohol-extended fuels ONLY if the alcohol
content does not exceed:
•
10% ethanol by volume
•
5% methanol with 5% cosolvents by volume
When using alcohol-extended fuels , be aware of
the following:
•
The boat’s fuel system may have different
requirements regarding the use of alcohol fuels.
Refer to the boat’s owner guide.
•
Alcohol attracts and holds moisture that can
cause corrosion of metallic parts in the fuel sys-
tem.
•
Alcohol blended fuel can cause engine perfor-
mance problems.
•
All parts of the fuel system should be inspected
frequently and replaced if signs of deterioration
or fuel leakage are found. Inspect at least annu-
ally.
IMPORTANT:
Always use fresh gasoline. Gaso-
line will oxidize, resulting in loss of octane and vol-
atile compounds, as well as the production of gum
and varnish deposits which can damage the out-
board.
Additives
IMPORTANT:
The only fuel additives approved
for use in Evinrude outboards are 2+4 ® fuel condi-
tioner and Evinrude/Johnson Fuel System Clean-
er. Use of other fuel additives can result in poor
performance or engine damage.
Evinrude/Johnson 2+4 Fuel Conditioner will help
prevent gum and varnish deposits from forming in
fuel system components and will remove moisture
from the fuel system. It can be used continuously
and should be used during any period when the
outboard is not being operated on a regular basis.
Its use will reduce spark plug fouling, fuel system
icing, and fuel system component deterioration.
Evinrude/Johnson Fuel System Cleaner will help
keep fuel injectors in optimal operating condition.

WARNING
Gasoline is extremely flammable and highly
explosive under certain conditions. Improper
handling of fuel could result in property dam-
age, serious injury or death.
Always turn off the outboard before fueling.
Never permit anyone other than an adult to
refill the fuel tank.
Do not fill the fuel tank all the way to the top
or fuel may overflow when it expands due to
heating by the sun.
Remove portable fuel tanks from the boat
before fueling.
Always wipe off any fuel spillage.
Do not smoke, allow open flames or sparks,
or use electrical devices such as cellular
phones in the vicinity of a fuel leak or while
fueling.
