Choke 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. Gradually re-
turn the choke knob to its home position
as the engine warms up.

cooling water pilot hole.
CAUTION:
ECM00511
A continuous flow of water from the cool-
ing water pilot hole shows that the water
pump is pumping water through the cool-
ing passages. If water is not flowing out
of the hole at all times while the engine is
running, overheating and serious dam-
age 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 problem cannot be located
and corrected.
