Operation
6. After the engine starts, slowly return the
manual starter handle to its original posi-
tion before releasing it.
7. Slowly return the throttle grip to the fully
closed position.
TIP:
When the engine is cold, it needs to be
●
warmed up. For further information, see
page 40.
If the engine does not start on the first try,
●
repeat the procedure. If the engine fails to
start after 4 or 5 tries, open the throttle a
small amount (between 1/8 and 1/4) and try
again. Also if the engine is warm and fails to
start, open the throttle a same amount and
try to start the engine again. If the engine
still fails to start, see page 65.

Cooling water

Check for a steady flow of water from the cool-
ing water pilot hole. A continuous flow of water
from the pilot hole indicates that the water
pump is pumping water through the cooling
water passages. If the cooling water passag-
es are frozen, it may take a while for water to
start flowing out of the pilot hole.

NOTICE
If water is not flowing out of the pilot hole
at all times while the engine is running,
overheating and serious damage could
occur. Stop the engine and check whether
the cooling water inlet on the lower case or
the cooling water pilot hole is blocked.
Consult your Yamaha dealer if the prob-
lem cannot be located and corrected.

3 minutes to warm up. Failure to do so will
shorten engine life.
2. Be sure the low oil pressure-alert indica-
tor goes off after starting the engine.
NOTICE: If the low oil pressure-alert
indicator blinks after the engine starts,
