Operation
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.
TIP:
●When the engine is cold, it needs to be warmed up. For further information, see page 33.
●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 54.

Cooling water
Check for a steady flow of water from the cooling water pilot hole. A continuous flow of water from the pilot hole shows that the water pump is pumping water through the cooling passag- es. If the cooling 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 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.

Choke start models
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.
