Fuel Containing Alcohol; Low Permeation Fuel Hose Requirement; Crankcase Oil; Oil Recommendations - Mercury Racing 1100 STERNDRIVE Operation, Maintenance & Warranty

These reformulated fuels are acceptable for use in your Mercury
engine.

FUEL CONTAINING ALCOHOL

If the fuel in your area contains either methanol (methyl alcohol) or
ethanol (ethyl alcohol), you should be aware of certain 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 fuel can absorb moisture from the air, resulting in a separation of
the water/alcohol from the gasoline in the fuel tank.
The fuel system components on your Mercury 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).
Fuel containing alcohol may increase:
• Corrosion of metal parts.
• Deterioration of rubber or plastic parts.
• Fuel permeation through rubber fuel lines.
• Starting and operating difficulties.
IMPORTANT: Operating a Mercury Marine engine with gasoline
containing alcohol creates unique problems as a result of long
storage periods common to a boat. Cars normally consume
alcohol‑blend fuels before they absorb enough moisture to cause
problems; however, boats often sit idle long enough for phase
separation to occur. In addition, alcohol can wash protective oil films
from internal components causing corrosion.

IMPORTANT: Because of possible adverse effects of alcohol in
gasoline, it is recommended that only alcohol‑free fuel 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.

OW ERMEATION UEL OSE EQUIREMENT
Low permeation fuel hose must be installed on all sterndrive engine
packages that are manufactured for sale, sold, or offered for sale in
the United States.
• The Environmental Protection Agency (EPA) requires that any
sterndrive engine package manufactured after January 1,
2009, must use low permeation fuel hose for the primary fuel
hose connecting the fuel tank to the engine.
• Low permeation hose is USCG Type B1‑15 or Type A1‑15,
defined as not exceeding 15/gm²/24 h with CE 10 fuel at
23 °C as specified in SAE J 1527 ‑ marine fuel hose.
