● When the engine is cold, it needs to be
warmed up. For further information, see
page 33.
● 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 54.

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 shows that the water pump
is pumping water through the cooling passag-
es. If the cooling passages are frozen, it may
take a while for water to start flowing out of the
pilot hole.
NOTICE
ECM01810
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.
Check that no water leaks from the joints be-
tween the exhaust cover, cylinder head, and
body cylinder.

Choke start models
After starting the engine, allow it to idle for 3
minutes to warm up. Failure to do so will
shorten engine life. Gradually return the
choke knob to its home position as the engine
warms up.
