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.
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 Mercury Marine 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.
Oil Recommendation
Recommended Oil
Mercury or Quicksilver Premium 2‑Cycle TC‑W3
Outboard Oil
IMPORTANT: Oil must be NMMA certified TC‑W3 2‑Cycle oil.
Mercury or Quicksilver Premium TC‑W3 2‑Cycle oil is recommended for this
engine. For added protection and lubrication, Mercury or Quicksilver Premium
Plus TC‑W3 2‑Cycle oil is recommended. If Mercury or Quicksilver outboard oil
is not available, substitute another brand of 2‑cycle outboard oil that is NMMA
Certified TC‑W3. Severe engine damage may result from use of an inferior oil.
Mixing Fuel and Oil
Use a 25:1 (4%) gasoline/oil mixture in the first tank of fuel.
After the break‑in fuel mixture is used up, use a 50:1 (2%) gasoline/oil mixture.
Refer to the table (following) for mixing ratios.
