Maintenance
6. Run the engine at a fast idle for a few
minutes in neutral position.
7. Just prior to turning off the engine, quickly
spray "Fogging Oil" alternately into each
carburetor or the fogging hole of the si-
lencer cover, if equipped. When properly
done, the engine will smoke excessively
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 teaspoon-
ful 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.
