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 mis-
use of the engine, and damage cause d
thereby will not be covered under the lim-
ited warranty.
ENOM00031-A
FUEL RATING
TOHATSU engines will operate satisfac-
torily when using a major brand of
unleaded gasoline meeting the following
specifications:
USA and C anada — 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 pre-
mium gasoline of 98 RON is also allowed.
ENOM00032-A
GASOLINES CONTAINING
ALCOHOL
The fuel system components on your
TOHATSU engine will withstand up to
10% ethyl alcohol (hereinafter referred
to as the "ethanol"), content in the gaso-
line. But even if the gasoline in your area
contains ethanol less than 10%, you
should be aware of cer tain adverse
effects that can occur. Increasing the
percentage 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 separation 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
suspected in the gasoline, it is recom-
mended 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 gas-
oline and contact our dealer immedi-
ately.
If the outboard motor will only be used
infrequently, please see the remarks on
fuel deterioration in the STORAGE chap-
ter (P 87) for additional information.
ENOW00020-1
CAUTION
When operating a TOHATSU engine on gaso-
line containing alcohol, storage of gasoline
in the fuel tank for long periods should be
avoided. Long periods of storage, create
unique problems. In cars, alcohol blend
fuels normally are consumed before they
can absorb enough moisture to cause trou-
ble, but boats often sit idle long enough for
