adverse effects that can occur. These
adverse effects are more severe with
methanol. Increasing the percentage of
alcohol in the fuel can also worsen these
adverse effects. Some of these adverse
effects are caused because the alcohol in
the gasoline can absorb moisture from the
air, resulting in a separation of the water/
alcohol from the gasoline in the fuel tank.
These may cause increased:
z
Corrosion of metal parts
z
Deterioration of rubber or plastic parts
z
Fuel permeation through rubber fuel
lines
z
Starting and operating difficulties
ENOW00018-0
Fuel leakage can cause fire or explosion,
potentially leading to severe injury or loss
of life. Every fuel system part should be
checked periodically, and especially after
long term storage, for fuel leak, change of
hardness of rubber, expansion and/or cor-
rosion of metals. In case any indication of
fuel leakage or degradation of fuel part is
found, replace relevant part immediately
before continuing operation.
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.
Damages resulting from the use of gaso-
lines that contain alcohol are not covered
under the limited warranty.
Fuel tank capacity:
12 liters (3.17 U.S. gal)
Fuel Tank: When using a fixed fuel tank in
place of genuine fuel tank, it is recom-
mended to select a one with a structure
facilitating interior cleaning.
ENOW00019-0
Do not fill the fuel tank over capacity. The
rise of gasoline temperature may cause
gasoline to expand which, if overfilled, may
leak through air vent screw when it is open.
Leaking gasoline is a dangerous fire haz-
ard.
ENOW00020-0
When operating a TOHATSU engine on
gasoline containing alcohol, storage of
gasoline in the fuel tank for long periods
should be avoided. Long periods of stor-
age, common to boats, create unique prob-
lems. In cars, alcohol blend fuels normally
are consumed before they can absorb
enough moisture to cause trouble, but
boats often sit idle long enough for phase
separation to take place. In addition, inter-
nal corrosion may take place during stor-
age if alcohol has washed protective oil
films from internal components.
