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 ethe r (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 alcoho l-extended fue ls, 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 blend ed fuel ca n cause engine pe rfor-
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 ap proved
for use in Evinrude outboards are 2+4
®
fuel condi-
tioner a nd Evinrude/Johnson Fue l System
Cleaner. Use of other fuel additives can res ult
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 period
when the outboard is not being operated on a reg-
ular basis. It s use will reduce sp ark plug fo uling,
fuel system icing, and fuel system compone nt
deterioration.
Evinrude/Johnson Fuel System Cle aner will
help keep fuel injectors in optimal operating condi-
tion.
A WARNING
Gasoline is e xtremely flammable and
highly explosive under certain conditions.
Improper handling of fue l could result in
property damage, serious injury or death.
Always turn off the ou tboard before fuel -
ing.
Never pe rmit anyone ot her than an adul t
to refill the fuel tank.
Do not fill the fuel t ank all the way to the
top or fuel may overflow when it e xpands
due to heating by the sun.
Remove portable fuel t anks from the boa t
before fueling.
Always wipe off any fuel spillage.
Do not s moke, allow op en fla mes or
sparks, o r use e lectrical devices su ch as
cellular phones in the vicinity of a fuel leak
or while fueling.
