Using Your Evinrude E-TEC Outboard
Minimum Octane
Your outboard is certified to operate on un-
leaded automotive gasoline with an octane
rating equal to or higher than:
• 87 (R+M)/2 AKI — Inside the U.S.
• 90 RON — Outside the U.S.
Using unleaded gasoline that contains methyl
tertiary butyl ether (MTBE) is acceptable
ONLY if the MTBE content does not exceed
15% by volume.
Alcohol Fuels
Your outboard has been designed to operate
using the specified fuels; however, 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 blended fuel may cause engine per-
formance problems.
NOTICE
Alcohol attracts and holds
moisture that can cause corrosion of
metallic parts in the fuel system.
Using alcohol-extended fuels is acceptable
ONLY if the alcohol content does not exceed:
• 10% ethanol by volume; or
• 5% methanol with 5% cosolvents by volume.
FUEL ADDITIVES
The only fuel additives approved for use in
your Evinrude E-TEC outboard are:
• Evinrude/Johnson 2+4 Fuel Conditioner
• Evinrude/Johnson Fuel System 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
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.

FUEL SYSTEM INFORMATION
Connecting the Fuel Hose
1) If the fuel hose is disconnected for any rea-
son, seal it to prevent spillage. Cap the fuel
fitting to prevent contamination.
2) Connect the fuel hose to the 3/8 in. (9 mm)
fuel fitting. Fasten hose securely with
clamp (18.5 mm) from owner's kit.
1. Fuel hose – 3/8 in. (9 mm)
WARNING
If engine is equipped with a quick-
disconnect fuel hose, you MUST
disconnect the fuel hose from the
engine and the fuel tank to prevent
fuel leaks:
• Whenever the engine is NOT being
used
• Whenever the engine is being trail-
ered
• Whenever the engine is in storage
NOTE: A small amount of fuel may
be released when the fuel connector
is disconnected.
Store portable fuel tanks in well-ven-
tilated
areas,
sources and open flames. Close the
vent screw of the fuel tank cap, if
equipped, to prevent escape of fuel
or fuel vapors which could acciden-
tally ignite. Do not allow discon-
nected fuel hoses to leak fuel.
IMPORTANT: Fuel distribution hoses in the
boat must deliver fuel at the rate of flow need-
ed by the outboard. Minimum inside diameter
of fuel hoses must be 3/8 in. (9 mm).
