Avoiding Fuel Flow Restrictions

Avoid engine damage. Adding components to the fuel supply system,
such as filters, valves, fittings, etc., may restrict the fuel flow. This
condition may cause the engine to stall at low speeds and create lean
fuel conditions at high speeds, causing engine damage.

Fuel Requirements

Use a major brand of unleaded gasoline, preferably without alcohol.
Avoid equipment damage. Use of improper fuel can seriously damage
your engine. Engine damage resulting from the use of improper fuel is
considered engine misuse and is not covered under the limited warranty.

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.
1. Mercury Marine does not recommend using leaded gasoline. Read the
information in the Fuel Containing Alcohol section.
2. Mercury Marine does not recommend using leaded gasoline. Leaded gasoline
is acceptable in areas where unleaded gasoline is not available; however,
exhaust passageway corrosion may occur due to the accumulation of exhausted
lead particles. Automotive fuels that contain fuel injector cleaner are
recommended for added internal cleanliness.
