Abstract

See full text

A dog clutch selectively meshes with a forward gear and a reverse gear according to an operation of a shift operating member such that connection of the forward gear or the reverse gear to a propeller shaft is changed. A friction clutch transmits the rotation of a drive shaft to the propeller shaft by a first friction surface and a second friction surface contacting together. Before a shifting stage in which the dog clutch meshes with the forward gear or with the reverse gear, a control unit is configured or programmed to control an actuator so as to execute synchronization control by making the first friction surface and the second friction surface of the friction clutch contact one another.
