WARNING
You could be seriously injured if the en-
gine accidentally starts when you are near
the propeller.
Before inspecting, removing, or install-
G
ing the propeller, remove the ignition
coils from the spark plugs. Also, place
the shift control in neutral, turn the main
switch to "
" (off) and remove the key,
and remove the clip from the engine
shut-off switch. Turn off the battery cut-
off switch if your boat has one.
Do not use your hand to hold the propel-

ler when loosening or tightening the

the anti-cavitation plate and the propel-
ler to prevent the propeller from turning.

Disconnect the fuel line from the motor.
2.
Install the flushing attachment over the
cooling water inlet. NOTICE: Do not run
the engine without supplying it with
cooling water. Either the engine water
59
pump will be damaged or the engine
will be damaged from overheating. Be-
fore starting the engine, be sure to
supply water to the cooling water pas-
sages. Avoid running the outboard
motor at high speed while on the
flushing attachment, otherwise over-
heating could occur.

3.
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 necessary
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.
A flushing attachment is available from your
G
Yamaha dealer.
If the overheat alert device is activated, turn
G
the engine off, and consult your Yamaha
dealer.
