The fuel system components on your MerCruiser engine will withstand up to 10% alcohol content in the gasoline.
We do not know what percentage your boat’s fuel system will withstand. Contact your boat manufacturer for
specific recommendations on the boats fuel system components (fuel tanks,fuel lines, and fittings). Be aware
that gasolines containing alcohol may cause increased:
•
Corrosion of metal parts.
•
Deterioration of rubber or plastic parts.
•
Fuel permeation through rubber fuel lines.
•
Starting and operating difficulties.
! 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, particularly after storage. All fuel components including fuel tanks, whether plastic metal
or fiberglass, fuel lines, fittings, fuel filters and carburetors/fuel injection components should be
inspected for leakage, softening, hardening, swelling or corrosion. Any sign of leakage or deterioration
requires replacement before further engine operation.
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 presence 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
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 has washed protective oil films from
internal components.

Crankcase Oil
To help obtain optimum engine performance and to provide maximum protection, we strongly recommend the
use of Quicksilver 4-Cycle Marine Engine Oil. If not available, a good grade, straight weight, detergent
automotive oil of correct viscosity, with an API classification of SH,CF/CF-2, may be used.
The chart below is a guide to crankcase oil selection. Oil filter should always be changed with oil.
In those areas where recommended straight weight oil is not available, a multiviscosity 20W-40 (SH, CF/CF-2)
or, as a second but less preferable choice, 20W-50 (SH,CF/CF-2) may be used.
IMPORTANT: The use of non-detergent oils, multi-viscosity oils (other than 20W-40 or 20W-50), low
quality oils or oils which contain solid additives, are specifically not recommended.
