PERATION
The ClearCommand Marine Propulsion Control System (hereafter
referred to as ClearCommand or System) is electronic and requires
a 12 or 24 VDC power supply, one Processor per engine/clutch and
one Control Head per remote station. The ClearCommand com-
mands the vessel’s throttle and shift using a single Control Head
lever.
One electric cable per Control Head lever connects the remote sta-
tion(s) to the Processor(s). Only one remote station will have com-
mand at a given time and the Station-in-Command is indicated by a
red light located on the Control Head. Station transfer is accom-
plished by pressing the Control Head mounted transfer button
