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.

Lubrication

1. Install the spark plug(s) and torque to
proper specification. For information on
spark plug installation, see page 46.
2. Change the gear oil. For instructions, see
page 51. Inspect the oil for the presence
of water that indicates a leaky seal. Seal
replacement should be performed by an
authorized Yamaha dealer prior to use.
3. Grease all grease fittings. For further de-
tails, see page 45.
TIP:
For long-term storage, fogging the engine
with oil is recommended. Contact your
Yamaha dealer for information about fogging
oil and procedures for your engine.

motor
Check the outboard motor for scratches,
nicks, or flaking paint. Areas with damaged

clean and paint the areas. A touch-up paint is
