Fuel Requirements
Minimum Octane
Evinrude/Johnson
outboards are certified to oper-
ate on unleade d automotive ga soline with an
octane rating equal to or higher than:
•
87 (R+M)/2 AKI, or
•
90 RON
Use unleaded gasolin e tha t co ntains met hyl ter-
tiary butyl ether (MTBE)
ONLY
if the MTBE con-
tent does not exceed 15% by volume.
Use alcoho l-extended fue ls
ONLY
if th e alcoh ol
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 b oat’s fuel system may h ave different
requirements regarding the use of alcohol fuels.
Refer to the boat’s owner guide.
•
Alcohol at tracts and ho lds moisture that can
cause corrosion of metallic parts in the fuel sys-
tem.
•
Alcohol blended fuel ca n cause engine pe rfor-
mance problems.
•
All parts of the fuel system should be inspected
frequently and replaced if signs of deterioratio n
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.

The only fuel additives ap proved
for use in
Evinrude
outboards are

Cleaner.
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 form-
ing in fue l syste m co mponents and will re move
moisture from the fuel system. It can be used con-
tinuously an d should be use d during any perio d
when the outboard is not being operated on a reg-
ular basis. It s use will reduce sp ark plug fouling,
fuel system icing, and fuel system compone nt
deterioration.
Evinrude/Johnson Fuel System Cleaner
will
help keep fuel injectors in optimal operating condi-
tion.

highly explosive under certain conditions.
Improper handling of fuel could result in
property damage, serious injury or death.
Always turn off the outboard before fuel-
ing.
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.
