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
passages. If water is not flowing out of
the 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 casing is blocked. If the prob-
lem cannot be found and corrected, con-
sult your Yamaha dealer.
