Maintenance
65
A flushing attachment is available from your
Yamaha dealer.
(5) Run the engine at a fast idle for a few
minutes in neutral while supplying fresh
water. WARNING! Do not touch or re-
move electrical parts when starting or
during operation. Keep hands, hair,
and clothes away from the flywheel
and other rotating parts while the en-
gine is running.
[EWM00092]
When using the flushing attachment, main-
tain adequate water pressure so that there
is a steady flow of water from the cooling
water pilot hole.
If the overheat alert device is activated, turn
the engine off, and consult your Yamaha
dealer.
(6) Just prior to turning off the engine, quick-
ly spray “Yamaha Stor-Rite Engine Fog-
ging Oil” into the intake silencer. When
properly done, the engine will smoke ex-
cessively and almost stall.
(7) Turn off the water supply, and then re-
move the flushing attachment and wipe
off any excess water.
(8) Install the top cowling and propeller.
(9) Drain the cooling water completely out of
the outboard motor. Clean the exterior of
the outboard motor thoroughly.

(2) Lubricate all grease fittings. For further
details, see page 72.
For long-term storage, fogging the engine
with fogging oil is recommended. Contact
your Yamaha dealer for information about
fogging oil and procedures for your outboard
motor.
