Lubrication; Cleaning And Anticorrosion Measures; Cleaning The Outboard Motor - Yamaha F2.5 Owner's Manual

Maintenance
5. Fill the tank with fresh water to above the
level of the anti-cavitation plate. NOTICE:
If the fresh water level is below the lev-
el 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 of the engine is mandatory to pre-
vent excessive engine damage due to
rust. Perform the flushing and fogging 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 10–15
minutes in neutral position.
8. Just prior to turning off the engine, quickly
spray "Yamaha Stor-Rite Engine Fogging
Oil" alternately into each carburetor or the
fogging hole of the silencer cover, if
equipped. When properly done, the en-
gine will smoke excessively and almost
stall.
9. Remove the outboard motor from the test
tank.
10. Drain the cooling water completely out of
the motor. Clean the body thoroughly.
11. Install the silencer cover/cap and top
cowling.

of water that indicates a leaky seal. Seal
replacement should be performed by an
authorized Yamaha dealer prior to use.

tails, see page 47.
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.
