CONTROL SYSTEM
Control systems permit the remote operation of the
engine's throttle and shift mechanisms. Certain
models include separate shift and throttle levers with
shift cables. Other Scarab models with either a single
engine or twin engine utilize an electronic shift/throttle
control body and "fly-by-wire" technology. Either style
of control allows you to select forward or reverse gear
and regulate engine speed. Always ensure shifting is
done at low engine speed.
A "start-in-neutral-only" feature which prevents starting
in gear is included. Refer to B-1A Neutral Safety
Switch in this section. Also, the shift lever and side
mount control have a neutral lock release to prevent
accidental shifting. It must be depressed to permit
shifting from neutral to for ward or reverse. See
Figures B1 and B2.

NOTICE
Allow the engine(s) to warm up before en-
gaging the shift control. Monitor all instruments
while engine is idling during warm up.
A. Neutral Safety Switch
Every control system has a neutral safety switch incor-
porated into it. This device prohibits the engine from
being started while the shift lever is in any position
other than the neutral position. If the engine will not
start, slight movement of the shift lever may be
necessary to locate the neutral position and disen-
gage the safety cutout switch. Control or cable
adjustments are required to correct this condition
should it persist. See your Scarab dealer for neces-
sary control and cable adjustments.
B. Emergency Engine Shut Off Switch
This safety device automatically stops the engine if
the lanyard is attached to the operator and the
operator falls from his helm station. Refer to the
manufacturer's literature for additional information
about using this switch.
The emergency engine shut off switch (Figure B4)
incorporates a shut off (interrupter) switch, switch clip,
lanyard, and lanyard clip. The lanyard clip must be
securely attached to the operator's PFD, clothing,
arm, or leg. Be sure to attach the lanyard to a place
where it is free of obstructions and to something that
will move with the operator if he or she leaves the
helm station. If the engine shuts down because this
switch was activated, the clip must be reinstalled on
the interrupter switch before the engine can be
restarted.
