发明名称 Boat propulsion unit and boat
摘要 A boat is capable of preventing shocks on gears in meshing engagement with each other and an abrupt movement thereof when a remote control shift lever is quickly rotated to reverse from a cruising mode. A control microcomputer is arranged to control the operation of a shift actuator based on the displacement of a remote control shift lever for remotely switching between forward, neutral, and reverse positions. The control microcomputer has a shift detector arranged to detect whether a shift operation from the neutral position to the forward position or the reverse position was made based on a signal from a lever position sensor arranged to detect the position of the remote control shift lever; and a switch control which does not drive a shift motor when a shift operation from the neutral position to the forward position or the reverse position is detected by the shift detector and the engine rotational speed detected by the engine rotational speed sensor is higher than a prescribed value, and drives the shift motor and controls a shift operating device to start shifting when the engine rotational speed decreases to a value equal to or smaller than the prescribed value.
