1. Flushing attachment
5. Cooling system flushing is essential to
prevent the cooling system from clogging
up with salt, sand, or dirt. In addition, fog-
ging/lubricating the engine is mandatory
to prevent 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.
TIP:
When using the flushing attachment, main-
G
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
G
the engine off, and consult your Yamaha
dealer.
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 the in-
take silencer or the fogging hole of the si-
lencer cover, if equipped. When properly
done, the engine will smoke excessively
and almost stall.
