ABSTRACT:
A shift system for a boat propulsion unit is provided comprising a remote control operation device having a remote control shift lever for shifting from a distance. A boat propulsion unit has a shift device for shifting and a shift actuator for actuating the shift device. A controller controls the actuation of the shift actuator according to the operation amount of the remote control shift lever, as the remote control shift lever is operated from a neutral position within a specified range of shift region. The controller controls the actuation amount of the shift actuator per unit operation amount of the remote control shift lever to be different in part of the shift region.
