6.
After the engine starts, slowly return the
manual starter handle to its original posi-
tion before releasing it.
7.
Slowly return the throttle grip to the fully
closed position.
NOTE:
●
When the engine is cold, it needs to be
warmed up. For further information, see
page 17.
●
If the engine does not start on the first try,
repeat the procedure. If the engine fails to
start after 4 or 5 tries, open the throttle a
small amount (between 1/8 and 1/4) and try
again. Also if the engine is warm and fails to
start, open the throttle a same amount and
try to start the engine again. If the engine
still fails to start, see page 39.

1.
After starting the engine, allow it to idle for
3 minutes to warm up. Failure to do so will
shorten engine life. Gradually return the
choke knob to its home position as the
engine warms up.
2.
Check for a steady flow of water from the
cooling water pilot hole.
CAUTION:
ECM00510
A flow of water from the hole on the ex-
haust cover shows that the water pump is
pumping water through the cooling pas-
sages. If water is not flowing out of the
hole at all times while the engine is run-
ning, overheating and serious damage
could occur. Stop the engine and check
whether the cooling water inlet on the low-
er case or the cooling water pilot hole is
blocked. Consult your Yamaha dealer if
the problem cannot be located and cor-
rected.
