WARNING
Outside the U.S.
Your outboard has been designed to operate using
the above fuels; however, be aware of the follow-
ing:
The boat’s fuel system may have different require-
ments 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 system.
Alcohol blended fuel can cause engine perfor-
mance problems.
Gasoline is extremely flammable and highly
explosive under certain conditions. Follow
the instructions in this section explicitly.
Improper handling of fuel could result in
property damage, serious injury, or death.
Always turn off the engine 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.
IMPORTANT: Always use fresh gasoline. Gasoline
will oxidize and weather; the result is loss of octane,
volatile compounds, and the production of gum and
varnish deposits which can damage the outboard.
Remove portable fuel tanks from the boat
before fueling.
Always wipe off any fuel spillage.
WARNING
Do not smoke, or allow open flames or
sparks, or use electrical devices such as
cellular phones in the vicinity of a fuel leak
or while fueling.
Leaking fuel is a fire and explosion hazard.
All parts in the fuel system should be
inspected frequently and replaced if signs
of deterioration or leakage are found.
Inspect the fuel system each time you
refuel, each time you remove the engine
cover, and annually.
Always work in a well-ventilated area.
Your outboard is certified to operate on unleaded
automotive gasoline with an octane rating equal to
or higher than that specified in Minimum Octane
chart. When using gasoline that contains MTBE or
alcohol, follow these guidelines:
OIL
Using unleaded gasoline that contains methyl ter- Evinrude/Johnson XD25™ Formula outboard
tiary butyl ether (MTBE) is acceptable ONLY if the oil is recommended for your outboard. It con-
MTBE content does not exceed 15% by volume.
Using alcohol-extended fuels is acceptable ONLY if
the alcohol content does not exceed:
tains a richer additive package than other TC-W3
oils, minimizing carbon build-up and deposits on
pistons and bearing surfaces. It provides 25%
greater detergency than minimum TC-W3 require-
ments.
10% ethanol by volume; or
5% methanol with 5% cosolvents by volume
Evinrude/Johnson brand oils are formulated to give
best engine performance while controlling piston
and combustion chamber deposits, providing supe-
rior lubrication and ensuring maximum spark plug
life.
If Evinrude/Johnson XD25 Formula outboard oil is
not available, you must use an NMMA-certified TC-
W3 oil such as Evinrude/Johnson direct injection oil
or Evinrude biodegradable outboard oil.
IMPORTANT: Failure to follow this recommenda-
tion could void the engine warranty if a lubrication-
related failure occurs.
