Maintenance
Store the outboard motor in a dry, well-

ventilated place, not in direct sunlight.

Procedure

Flushing in a water tank
1. Wash the outboard motor body using
fresh water. For further information, see
page 28.
2. Place the fuel cock in the closed position
and disconnect the fuel line if equipped.
Tighten the air vent screw, if equipped.
3. Remove the engine top cowling and si-
lencer cover.
4. Install the outboard motor on the test
tank.
1. Water surface
2. Lowest water level
5. Fill the tank with fresh water to above the
level of the anti-cavitation plate.
CAUTION:
If the fresh water level is below the level of
the anti-cavitation plate, or if the water
supply is insufficient, engine seizure may
occur.
6. Cooling system flushing is essential to
prevent the cooling system from clogging
up with salt, sand, or dirt. In addition, fog-
ging/lubricating of the engine is mandato-
27
ry to prevent excessive engine damage
due to rust. Perform the flushing and fog-
ging at the same time.
WARNING
Do not touch or remove electrical parts

when starting or during operation.
Keep hands, hair, and clothes away from

the flywheel and other rotating parts
while the engine is running.
7. Run the engine at a fast idle for a few
minutes in neutral position.
8. 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.
If "Fogging Oil" is not available, run the
9.
engine at a fast idle until the fuel system
empties and the engine stops.
10. Remove the outboard motor from the test
tank.
11. Install the silencer cover or fogging hole
cap, and the top cowling.
12. Drain the cooling water completely out of
the motor. Clean the body thoroughly.
13. If "Fogging Oil" is not available, remove
the spark plug(s). Pour a teaspoonful of
clean engine oil into each cylinder. Crank
several times manually. Replace the
spark plug(s).
14. Drain the fuel from both the built-in and
portable fuel tanks, on equipped models.
NOTE:
Portable fuel tank equipped models: Store the
portable fuel tank in a dry, well-ventilated
place, not in direct sunlight.
