Checks After Starting Engine; Cooling Water; Warming Up Engine; Warming Up - Yamaha F4 Owner's Manual

TIP:
It is not necessary to use the choke when
starting a warm engine, such as immediately
after the outboard motor has been operated
under a load.
5. Pull the manual starter handle slowly until
you feel resistance. Then give a strong
pull straight out to crank and start the en-
gine. If the engine does not start on the
first try, repeat the procedure.
6. After the engine starts, slowly return the
manual starter handle to its original posi-
tion before releasing it.
7. Warm up the engine. For further informa-
tion, see page 38.
8. Return the choke knob to its original posi-
tion gradually.
9. Slowly return the throttle grip to the fully
closed position.

Cooling water

Check for a steady flow of water from the cool-
ing water pilot hole. A continuous flow of water
from the pilot hole indicates that the water
pump is pumping water through the cooling
water passages. If the cooling water passag-
es 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 prob-
ZMU06746 lem cannot be located and corrected.
