PRE-OPERATING PREPARATIONS
ENOM00030-A
1. Fuel handling
ENOW000017-0
CAUTION
Use of improper gasoline can damage your
engine. Engine damage resulting from the
use of improper gasoline is considered
misuse of the engine, and damage caused
thereby will not be covered under the lim-
ited warranty.
ENOM00031-A
FUEL RATING
Evinrude engines will operate satisfactorily
when using a major brand of unleaded
gasoline meeting the following specifica-
tions:
USA and Canada — having a posted
pump Octane Rating of 87 (R+M)/2 mini-
mum. Premium gasoline (92 [R+M]/2
Octane) is also acceptable. Do not use
leaded gasoline.
O u t s i d e U S A a n d C a n a d a — U s e
unleaded gasoline with declared octane
rating of 91 RON or over. Use of premium
gasoline of 98 RON is also allowed.
ENOM00032-A
GASOLINES CONTAINING
ALCOHOL
The fuel system components on your
Evinrude engine will withstand up to 10%
ethyl alcohol (hererinafter referred to as the
"ethanol"), content in the gasoline. But if
the gasoline in your area contains ethanol,
you should be aware of certain adverse
effects that can occur. Increasing the per-
centage of ethanol in the fuel can also
worsen these adverse effects. Some of
these adverse effects are caused because
the ethanol in the gasoline can absorb
moisture from the air, resulting in a separa-
tion of the water/ethanol from the gasoline
in the fuel tank.
These may cause increased:
Corrosion of metal parts
Deterioration of rubber or plastic parts
Fuel permeation through rubber fuel
lines
Starting and operating difficulties
If the use of gasoline containing alcohol is
inevitable, or presence of alcohol is sus-
pected in the gasoline, it is recommended
to add a filter that has water separating
capability, and check the fuel system for
leaks and mechanical parts for corrosion
and abnormal wear more frequently.
And, in case any of such abnormality is
found, discontinue the use of such gaso-
line and contact our dealer immediately.
If the outboard motor will only be used
infrequently, please see the remarks on
fuel deterioration in the STORAGE chapter
(P 56) for additional information.

CAUTION
When operating a Evinrude engine on gas-
oline containing alcohol, storage of gaso-
line in the fuel tank for long periods should
be avoided. Long periods of storage, com-
mon to boats, create unique problems. In
cars, alcohol blend fuels normally are con-
sumed before they can absorb enough
moisture to cause trouble, but boats often
sit idle long enough for phase separation to
take place. In addition, internal corrosion
may take place during storage if alcohol
