A
control system for a marine vessel having one or more engines and a transmission associated with each engine is disclosed. The
control system includes one or more control stations, each having a
control arm and
arm position means coupled to the
control arm for providing an electrical
signal that represents a position of the
control arm within its operating range. The
system includes one or more electronic control units, each of which is electro-mechanically coupled to an engine and a transmission. A first
electronic control unit (ECU) includes input means for receiving the electrical
signal, control means for controlling a
throttle of a first engine and shift position of a first transmission based on the electrical
signal, and output means for providing a
control signal that represents a current position of the control arm to a second ECU. The second ECU is coupled to the first ECU via the communications link, and includes input means for receiving the
control signal from the first ECU, and control means for controlling the
throttle of a second engine and the shift position of a second transmission based on the power
train control signal.
