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
43
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
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-
" (start)
rected.

Warming up engine

After starting the engine, allow it to idle
for 3 minutes to warm up. Failure to do
so will shorten engine life.
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
