Abstract: An engine control apparatus includes a lever member, an input shaft, a potentiometer, an output gear, a motor, a shift arm, a reduction gear mechanism, and a force transmission mechanism. The force transmission mechanism includes a damper unit. When the lever member moves in a first direction or a second direction, the motor rotates based on an output of the potentiometer. The rotation of the motor is transmitted to the shift arm via the reduction gear mechanism. This moves the shift arm to a forward-side shift positon or a backward-side shift position. When the lever member is located within a predetermined angle from the neutral position, the damper unit deforms in a state where the output gear stops. This allows the rotation of the input axis.

Abstract: According to one embodiment, a shift actuator includes a main body section and a shaft section. The main body section has an electric motor which has a vertically extending rotating shaft, and a gear mechanism which rotates the shaft section in accordance with the rotating shaft. The shaft section has a threaded shaft extending parallel to the rotating shaft and made to rotate by the gear mechanism in accordance with the rotating shaft and a movable nut which is screwed onto the threaded shaft and moves upward or downward with rotation of the threaded shaft. The movable nut is connected with a shift member which changes the gears of a propeller shaft.
