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 B3)

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

started.

The Scarab jet boats are equipped with either a single

engine or twin engine side-mount con trol. This allows

you to select forward or reverse gear and regulate

engine speed and ensure shifting is done at low

engine speed.

a neutral lock button to prevent accidental shifting. It

must be pressed to permit shifting from neutral to

for ward or reverse. See Figure B1.
