WARNING
Fuel leakage is a fire or explosion hazard, which can cause serious injury or
death. Periodically inspect all fuel system components for leaks, softening,
hardening, swelling, or corrosion, particularly after storage. Any sign of
leakage or deterioration requires replacement before further engine
operation.
NOTICE
The use of improper fuel can cause serious damage to the engine. Damage
resulting from the use of improper fuel is considered engine misuse and is
not covered under the limited warranty. Use only the recommended fuel in
the engine.

USING REFORMULATED (OXYGENATED) FUELS (USA ONLY)
This type of fuel is required in certain areas of the U.S. The two types of
oxygenates used in these fuels are alcohol (ethanol) or ether (MTBE or ETBE).
If ethanol is the oxygenate that is used in the gasoline in your area, refer to the
Fuel Containing Alcohol section.
These reformulated fuels are acceptable for use in your Mercury engine.
FUEL CONTAINING ALCOHOL
Bu16 Butanol Fuel Blends
Fuel blends of up to 16.1% butanol (Bu16) that meet the published Mercury
Marine fuel rating requirements are an acceptable substitute for unleaded
gasoline. Contact your boat manufacturer for specific recommendations on
your boat's fuel system components (fuel tanks, fuel lines, and fittings).
1. Mercury Racing does not recommend using leaded gasoline. Leaded gasoline is acceptable in areas where
unleaded gasoline is not available; however, lead particles may build up in the exhaust passages and/or the
combustion chambers.
