ABSTRACT:
A remote control system is provided for transmitting control movement to a controlled member, such as a throttle or transmission control lever, on a marine propulsion unit from a selected one of a plurality of remote control units each of which has an operator movable between a plurality of positions. A remote control mechanism has at least one slidably supported control element operatively connected to each of the operators for linear reciprocation of the control elements upon movement of the respective operator. The remote control mechanism further includes a pinion gear operatively engaged with the control elements, a shaft connected for rotation with the pinion, and a pair of connecting links for converting the linear reciprocation of the control elements into a rotary motion of a spindle. A first rotation angle detecting device detects the rotational position of the spindle and transmits a signal to a control unit indicative of this rotational position. An actuator unit effects movement of the controlled member and is controlled by the control unit on the basis of the signal received from the first rotation angle detecting device. The invention may also include a second rotation angle detecting device for detecting the rotational position of a pinion gear of the actuator unit and transmitting a signal to the control unit indicative of this rotational position. When this additional detecting device is used, the actuator unit is controlled by the control unit on the basis of the signals received from both detecting devices to effect movement of the controlled member.
