Switches
Check the start switch 1, the engine stop
switch 2, and the engine shut-off switch 3
for proper operation.
To check these switches, place the water-
craft in the water to provide adequate cooling.
Start the engine, and then pull the engine
shut-off cord 5 to remove the clip 4 from the
engine shut-off switch. Verify that the engine
stops immediately. (See pages 2-7 to 2-9 for
information on proper operation of the start
switch, the engine stop switch and the engine
shut-off switch.)

Cooling water pilot outlet
Check that water comes out from the port
(left) pilot water outlet while the engine is
running and the watercraft is in the water.
(See page 2-9 for further instructions.)

2. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left wrist.
WARNING@ Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
NOTE:@ It is not possible to start the engine with the
clip removed from the engine shut-off
switch.
3. Push the start switch (green button).
NOTE:@ The engine will not start if the throttle lever is
squeezed.
4. Release the start switch as soon as the
engine starts to run.
CAUTION:@
Never push the start switch while the
engine is running.

Do not operate the start switch for
more than 5 seconds, otherwise the
battery will be discharged and the
engine will not start. Also, the starter
motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
then try again.
