GASOLINE CONTAINING ALCOHOL MAY INCREASE:
•
Corrosion of metal parts.
•
Deterioration of rubber or plastic parts.
•
Fuel permeation through rubber fuel lines.
•
Starting and operating difficulties and decrease in performance.
Because of possible adverse effects of alcohol in gasoline, it is
recommended that only alcohol-free gasoline be used where
possible. If only fuel containing alcohol is available, or if the pres-
ence of alcohol is unknown, increased inspection frequency for leaks
and abnormalities 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.
