The adverse effects of alcohol are more severe with methyl alcohol
(methanol) and are worse with increasing alcohol content.

WARNING
FIRE AND EXPLOSION HAZARD: Fuel leakage from any part of fuel system
can be a fire and explosion hazard which can cause serious bodily injury or
death. Careful periodic inspection of entire fuel system is mandatory, particu-
larly after storage. All fuel components including fuel tanks, whether plastic
metal or fiberglass, fuel lines, fittings, fuel filters and carburetors/fuel injec-
tion components should be inspected for leakage, softening, hardening,
swelling or corrosion. Any sign of leakage or deterioration requires replace-
ment before further engine operation.
Because of possible adverse effects of alcohol in gasoline, it is rec-
ommended that only alcohol-free gasoline be used where possible.
If only fuel containing alcohol is available, or if the presence of alco-
hol is unknown, increased inspection frequency for leaks and abnor-
malities is required.
IMPORTANT: When operating a MerCruiser engine on gasoline
containing alcohol, storage of gasoline in the fuel tank for long
periods should be avoided. Long periods of storage, common
to boats, create unique problems. In cars alcohol-blend fuels
normally are consumed before they can absorb enough mois-
ture 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 has washed protective
oil films from internal components.
Quicksilver Fuel System Treatment and Stabilizer (92-78383A12)
and Gasoline Stabilizer (92-817529A12) is highly recommended for
addition during storage periods. See "Cold Weather or Extended
Storage" later in this manual.
