5) Put the throttle levers in the idle
position. Shift into Neutral. Turn the
ignition key of one engine to "Start."
When the engine starts, release the
key. Repeat for the other engine. If
the engine will not start or doesn't
stay running, move the throttle
levers forward slightly and try again.
CAUTION:
Never turn the ignition key to "Start"
while the engine is running. Do not
keep the starter motor running for
more than five seconds. If the
engine does not start after five sec-
onds of cranking, release the starter
button. Wait at least 15 seconds
before trying to start the engine
again. If the starter motor is
engaged continuously for more than
five seconds, the battery will be
quickly discharged, and it will be
impossible to start the engine. The
starter motor may also be damaged
if it is engaged continuously for
more than five seconds.
NOTE:
● Be sure the shift lever is put in the
Neutral position or the starter motor
will not operate.
● On this boat, the engines are con-
nected directly to the drive unit.
Starting either engine generates
some thrust immediately. Only
enough throttle should be applied to
keep the engine at a fast enough
idle to stay running.
6) After the engines are warm, gradu-
ally push the choke knobs in fully,
back to their original position.
CAUTION:
Do not operate the jet boat with just
one engine running. Severe engine
damage could result because water
can flood the non-operating engine
through the cooling water intake. If
single-engine operation is unavoid-
able, operate the boat at a "no wake"
speed only.
