F. Four Position Ignition Switch
Most models use an ignition switch(es) with four
positions: OFF, ON/RUN, ACCESSORIES, and
START. The START position is spring loaded and the
key should be held in this position until the engine
starts but for no more than 5 seconds at a time. If
engine fails to start after 5 seconds release the key.
Wait 15 seconds and then try again. Once engine
starts, the key will return to the RUN position once
released.
DO NOT hold in START position for more
than 5 seconds. Holding the key in the
START position longer then 5 seconds will
quickly drain the start battery and thus be
unable to start the motor. Damage to the
starter motors is also possible.
While engine is running, never turn the
ignition key to the START position. Damage
to the starter may occur.
Always turn the key to the OFF position when the
engine(s) is not running. This will prevent discharging
of the battery(s). The ACCESSORIES position allows
the operator to run the stereo without activating the
other ship’s systems.
Should the boat be left unattended, be sure to
remove the key from the ignition to avoid possible
unauthorized use or theft.
G. Instrument Maintenance
Electrical protection for instruments and ignition
circuitry is provided by either by fuses or circuit
breakers depending on the model. On those models
utilizing fuses they are located in the fuse block which
is located in the helm console storage. The circuit
breakers are located on the battery switch panel. The
battery switch panel is typically located inside the port
stern seat storage compartment. Lift or remove the
port stern seat cushion to access the battery switch
panel.
Periodically, spray the ignition switch with a contact
cleaner. The ignition switch and all instruments,
controls, etc. should be protected from the weather
when not in use. Scarab offers appropriate weather
covers for each model. Excessive exposure can lead
to gauge and ignition switch difficulties.
DO NOT use a product such as WD-40 as a
contact cleaner. Be sure to read the label
before using any product.
Electronic gauges are affected by static electricity that
builds-up on the glass face. Periodic washing on the
gauge face with a dampened soft cloth and mild dish
detergent will help eliminate the static electricity
problem and improve gauge accuracy. Note: Do not
saturate gauges with water.
B - 5 ELECTRICAL SYSTEM
All electrical equipment on the Scarab jet boat models
operates on 12-Volt DC. Certain Scarab models come
equipped with a single battery system. The battery is
located typically in the port engine compartment
storage. Note: Location may vary depending on the
model and optional equipment installed.
