ABSTRACT:
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 actuating element that has both manual and electrical modes of operation. In the manual operation mode, a controlled element which is connected to the lever on the propulsion unit is actuated by a lever arm in response to movement of a first operator. In the electrical operation mode, the controlled element is actuated by a motor which is operated in response to electrical signals transmitted to the motor through a control unit from a position detector of the actuating element in response to movement of the first operator and from a position detector associated with the controlled element. A second remote operator is also provided for transmitting movement to the controlled element and lever on the propulsion unit. When this second operator is used, an electrical signal is transmitted from a position detector in response to movement of the second operator to the control unit which also receives a feedback signal from the position detector associated with the controlled element to control operation of the motor. A switch mechanism is provided for switching the actuating element between the first and second modes of operation. The switch mechanism preferably comprises a stopper pin that is selectively engageable with the lever arm for setting the actuating element in the first mode of operation and with a motor driven gear for setting the actuating element in the second mode of operation.
