WARNING
&
Gasoline
is
extremely
flammable
and
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.
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
INSTALLATION AND PREDELIVERY
FUEL AND
OIL
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. 2
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
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
fuel system components and will remove
moisture from the fuel system. It can
be
used con-
tinuously
and should
be
used during any period
when the outboard
is
not being operated
on
a reg-
ular
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 condi-
tion.
