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
ECM01811
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 wheth-
er the cooling water inlet on the lower
case or the cooling water pilot hole is
blocked. Consult your Yamaha dealer if
the problem cannot be located and cor-
rected.
