WARMING UP ENGINE

w
2-hp model: The propeller rotates when-
ever the engine is running. Do not move
the throttle control lever from the start
position during warm-up. The boat could
unexpectedly start to move, which could
result in an accident.
1) Before beginning operation, allow the
engine to warm up at idling speed for
3 minutes. (Failure to do this will
shorten engine life.)

2) Check a flow of water with exhaust
gas from the hole on exhaust cover.

2) Check for a steady flow of water from
the cooling-water pilot hole.
cC
A continuous flow of water from the pilot
hole shows that the water pump is
pumping water through the cooling pas-
sages. If water is not flowing out of the
309023*
pilot hole at all times while the engine is
running, do not continue to run the
engine. Overheating and serious damage
could occur. Stop the engine and check
to see if the water inlet on the lower cas-
ing is blocked. If the problem cannot be
found and corrected, consult your Yama-
ha dealer.
