Fuel System Treatment
1. If the boat is to be placed in storage with fuel in the
tank(s) that does not contain alcohol, fill the fuel
tank(s) with fresh fuel and a sufficient amount of Sta-
Bil gasoline stabilizer to treat the entire tank. Follow
instructions on the container.
2. If the boat is to be placed in storage with fuel that
contains alcohol, the fuel tank should be drained as
completely as possible and Sta-Bil gasoline stabilizer
added to any fuel remaining in the tank following the
instructions on the container.
3. Start the engine and operate at Idle RPM until the
engine reaches normal operating temperature. (If
using a hose and adapter, adjust the faucet to avoid
over-cooling the engine at low RPM.) Run the engine
for at least 15 minutes to ensure that the fuel stabiliz-
er enters the engine's fuel system.
Running the engine with the flame arrestor
removed increases the possibility of fire or
explosion if engine backfire occurs and
gasoline fumes are present. If the engine is
operated without the flame arrestor secured,
extreme care must be taken to ensure that
the engine compartment is well ventilated
and that no fuel leaks are present.
