Checks After Starting Engine; Cooling Water; Warming Up Engine; Choke Start Models - Yamaha 6c Owner's Manual

TIP:
When the engine is cold, it needs to be
●
warmed up. For further information, see
page 30.
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 53.

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 wa-
ter pump is pumping water through the cool-
ing passages. 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 wheth-
er 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 cor-
rected.

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 en-
gine warms up.
