Checks after starting engine

EMU36524

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.
ECM01811
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.

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.
