Warming Up Engine; Manual Start Models; Shifting; Forward (Tiller Handle And Remote Control Models) - Yamaha F2.5 Owner's Manual

Operation
If the engine does not start on the first try,
G
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 45.

Manual start models

1. After starting the engine, return the choke
knob to the halfway position. For approx-
imately the first 5 minutes after starting,
warm up the engine by operating at one
fifth throttle or less. After the engine has
warmed up, push the choke knob in fully.
Failure to do so will shorten engine life.
NOTE:
If the choke knob is left pulled out after the
G
engine starts, the engine will stall.
In temperatures of -5°C or less, leave the
G
choke knob pulled out fully for approximate-
ly 30 seconds after starting.
2. Check for a steady flow of water from the
cooling water pilot hole.
ECM00511
CAUTION:
A continuous flow of water from the cool-
ing water pilot hole shows that the water
pump is pumping water through the cool-
ing passages. If water is not flowing out of
the 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 low-
er case or the cooling water pilot hole is
23
blocked. Consult your Yamaha dealer if
the problem cannot be located and cor-
rected.

CAUTION:
To change the boat direction or shifting
position from forward to reverse or vice-
versa, first close the throttle so that the en-
gine idles (or runs at low speeds).
