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.
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.

Manual start and electric start models
1. After starting the engine, allow it to idle for
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,
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.
