Cold Engine Fails to Start
Prime start model
If a cold engine fails to start for prime
start model, use the following procedure.
w
When starting or operating the engine,
do not touch the ignition coil, high volt-
age wire, spark plug cap or other electri-
cal parts carrying high voltage. Keep
loose clothing and other objects away
from the engine when starting it with an
emergency starter rope. An unguarded
rotating flywheel is very dangerous. Do
not attempt to replace the top cowling
when the engine is running. Proceed at
once to the nearest port to get the engine
repaired. Take care to prevent water
splashing onto the flywheel.
1) Adjust the trim angle so that the drive
shaft is at right angles to the water
surface or is trimmed in.
2) Open the emergency starter valve
located behind the silencer cover on
the front side.
3) Squeeze the priming pump two or
001671
three times to feed fuel.
4) Open the throttle slightly without
shifting using the throttle control grip,
neutral throttle lever or free accelera-
tor. (It is necessary to change the
throttle opening slightly depending
on the engine temperature.)
After the engine starts, return the
throttle to the original position.
