NOTICE
To avoid starter motor overheating, the crank-
ing period should not exceed 5 - 10 seconds
and a rest period of 30 seconds should be
observed between cranking cycles to let the
starter cool down and its mechanism disen-
gage.
5. As soon as engine starts, release key and it will
automatically turn to the ON/RUN position.
6. Check steering operation. Turn steering wheel full
to port and starboard while observing jet nozzle(s)
movement.
7. After starting the engine and before engaging the
throttle/shifter, the operator must ensure the jet
nozzle is in the "straight ahead" position.
Steps to center the jet nozzle
a,
Rotate the steering wheel all the way in one
direction.
b.
Rotate the steering wheel all the way back in
the opposite direction, counting the number of
revolutions of the wheel as you do this.
c.
Lastly, rotate the wheel back again in the
opposite direction half as many revolutions as
it took to go completely in the other direction.
Prevent possible man-overboard situations.
Scarab jet boats are equipped with an ex-
tremely responsive steering and propulsion
system. Ensure jet nozzle is in the "straight
ahead" position before engaging throttle/
shifter.
8. Check tachometer to monitor engine rpms.
9. Once engine has warmed up, check to see if high
temperature warning message code is displayed.
If not displayed the engine temperature is stay-
ing within optimum range. If warning message is
displayed, stop engine immediately and inspect for
cause of high reading.
10. With engine running, verify that no high or low
voltage code is displayed. No message code indi-
cates that the battery is in good condition.
Operation - Section D
("straight ahead" position):
11. Inspect for fuel odors and visible leaks in the fuel,
oil, coolant, and exhaust systems.
12. Make sure boat is securely moored to the dock
and engine is idling. Then move the throttle for-
ward and then aft and back to neutral to check for
proper operation of the shifting motion. Be careful.
Leave the engine in gear for only a split-second.

CONTROL OPERATIONS
NOTICE
The control information included in this section is
general only. For specific operation of the controls
on your boat, refer to the control manufacturer's
literature and engine manufacturer's literature
included in your owner's packet. Ensure you
completely understand the operation of the con-
trols before operating your boat. Also consult your
dealer should any questions arise regarding the
operation of the control unit.
A. Maneuvering of the Separate Shift & Throttle
Control
Shifting and engine speed are controlled with the
separate levers. See Figure D4.
N - When the shift handle is in neutral position,
the impeller is turning. Reverse gate will be
in the middle position, directing half of the
thrust toward the front of the boat to minimize
movement.
F - Gate positioned for forward movement
(ahead).
R - Gate positioned for backward movement
(astern).
T - Engine speed control.
