gine is running. Do not keep the start-
er motor turning for more than 5
seconds. If the starter motor is turned
continuously for more than 5 seconds,
the battery will be quickly discharged,
thus making it impossible to start the
engine. The starter can also be dam-
aged. If the engine will not start after 5
seconds of cranking, return the main
switch to " " (on), wait 10 seconds,
then crank the engine again.

Cooling water

Check for a steady flow of water from the
cooling 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
passages 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.

Electric start models

1. After starting the engine, allow it to idle
for 3 minutes to warm up to provide max-
imum operating performance and accel-
eration. Failure to do so will shorten
engine life.
2. Be sure the low oil pressure-alert indica-
tor remains off after starting the engine.
NOTICE: If the low oil pressure-alert
indicator blinks after the engine starts,
stop the engine. Otherwise, serious
engine damage could occur. Check
the oil level and add engine oil if nec-
essary. Consult your Yamaha dealer if
the cause for the low oil pressure alert
cannot be found.
