6.
Run the engine at a fast idle for a few mi-
nutes in neutral position.
7.
Just prior to turning off the engine, quick-
ly spray “Fogging Oil” alternately into
each carburetor or the fogging hole of
the silencer cover, if equipped. When
properly done, the engine will smoke ex-
cessively and almost stall.
8.
Remove the outboard motor from the
test tank.
9.
Install the silencer cover/cap of fogging
hole and top cowling.
10. If the “Fogging Oil” is not available, run
the engine at a fast idle until the fuel sys-
tem becomes empty and the engine
stops.
11. Drain the cooling water completely out of
the motor. Clean the body thoroughly.
12. If the “Fogging Oil” is not available, re-
move the spark plug(s). Pour a tea-
spoonful of clean engine oil into each
cylinder. Crank several times manually.
Replace the spark plug(s).
13. Drain the fuel from the fuel tank.
TIP:
Store the fuel tank in a dry, well-ventilated
place, not in direct sunlight.

tails, see page 61.

For long-term storage, fogging the engine
