Fuel System Treatment
!
WARNING
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.
1. For winter storage, fill the fuel tank(s) with fresh fuel and a
sufficient amount of gasoline stabilizer to treat the entire tank.
Follow instructions on the container. Only use fuel stabilizer
products displaying the following mark on the label.
2. 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 stabilizer enters the engine’s fuel system.
NOTICE
Indmar does not recommend applying fogging oil while the engine
is running. The fogging oil could damage the catalytic converter.
The cylinders must be protected by removing the spark plugs and
applying the fogging oil directly into the cylinders (2-3 second
spray or one tablespoon of liquid fogging oil).
3. After all the cylinders have been treated, crank the engine to
spread the lubricant on the cylinder walls. Replace the spark
plugs in the engine.
4. Perform annual maintenance; refer to Section 7, Scheduled
Maintenance Chart.
