Boat control functions

Engine shut-off switch

WARNING
Always attach the engine shut-off cord
(lanyard) to your PFD before starting the
engines. Failure to attach the cord could
result in a runaway boat if the operator is
ejected.
Do not attach the cord to clothing that
could tear loose. Do not route the cord
in such a way that it could become en-
tangled, preventing it from functioning.
Avoid accidentally pulling the cord dur-
ing normal operation. Once the engines
have stopped, you have no steering con-
trol of the boat which could result in an
accident. Also, without engine power,
the boat could slow rapidly from planing
speed. This could cause people and ob-
jects in the boat to be thrown forward,
which could cause injury.
The clip on the end of the engine shut-off
cord (lanyard) must be attached to the engine
shut-off switch for the engines to run. The
cord must be attached to a secure place on
the operator's PFD. Should the operator fall
overboard or leave the helm, the cord will pull
out the clip, stopping the ignition to the both
engines. This will prevent the boat from run-
ning away under power.

Batteries and battery switches

The batteries and switch assembly are locat-
ed under the rear port seat.
This boat uses two marine batteries. One bat-
tery is designated as the start battery. The
start battery is connected to the starter cir-
cuits on both engines to provide current for
the starter motors.
The other battery is designated as the house
battery. The house battery provides power
for the various accessory circuits on the boat,
such as the circuits for lighting, bilge pump,
blowers and audio system.
