A remote control system for transmitting control movement to a controlled member, such as a throttle or transmission control lever on a marine propulsion unit, which includes an actuator unit having a lever arm for mechanically actuating the controlled member and an electric motor for electrically actuating the controlled member. A first remote control unit is provided which has a first operator mechanically connected to the lever arm for selectively transmitting movement to the lever arm upon movement of the first operator. There is also provided a second remote control unit having a second operator electrically connected to the electric motor through a central control unit for selectively transmitting an electrical signal to the central control unit for selectively transmitting movement to the electric motor upon movement of the second operator. Cables transmit movement of the lever arm and electric motor into movement of the controlled member while interlock switches and a locking mechanism preclude operation of the controlled member by one of the operators when the other of the operators is operated. The control state of the operators is indicated on selection display units.

DETAILED DESCRIPTION This invention is adapted to be embodied in a remote control system for transmitting control movement to a controlled member, such as a throttle or transmission control lever.
The remote control system comprises an actuator unit having manual actuating means and electric actuating means both operatively connected to the controlled member.
In accordance with the invention, a first remote control unit is provided which has a first operator mechanically connected to the manual actuating means for selectively transmitting movement to the manual actuating means upon movement of the first operator There is also provided in accordance with the invention a second remote control unit having a second operator electrically connected to the electric actuating means through a central control unit for selectively transmitting an electrical signal to the central control unit for selectively transmitting movement to the electric actuating means upon movement of the second operator.
The remote control system further includes means for transmitting movement of each of the actuating means into movement of the controlled member, interlock means for precluding operation of the controlled member by one of the operators when the other of the operators is operated, and means for indicating the control state of the operators.
