Checks after starting engine

EMU36522

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.

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.
