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.

Warming up engine

Electric start models
1.
After starting the engine, allow it to idle for
3 minutes to warm up to provide maxi-
mum 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 oil if necessary.
Consult your Yamaha dealer if the
cause for the low oil pressure-alert in-
dicator cannot be found.
