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, we recommend only
alcohol‑free gasoline when possible. If the only fuel available contains alcohol or if you do
not know whether the fuel contains alcohol, inspect for leaks and abnormalities more
frequently.
IMPORTANT: When operating a Mercury MerCruiser engine on gasoline containing
alcohol, do not store the gasoline in the fuel tank for long periods. Whereas cars normally
consume alcohol‑blend fuels before they can absorb enough moisture to cause trouble,
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.
Engine Oil
To help obtain optimum engine performance and to provide maximum protection, we
recommend using the following oil:
Application Recommended Oil
