Abstract

A vessel propulsion apparatus includes a dog clutch that selectively engages either a front gear or a rear gear, an intermediate shaft rotatably supported by the front gear and by the rear gear and that rotates together with the dog clutch, a propeller shaft to which rotation of the intermediate shaft is transmitted, a lower case containing a drive gear and other elements, and a thrust transmitting member that receives a forward-direction thrust from the propeller shaft and that transmits the thrust to the lower case without transmitting the thrust to the intermediate shaft.
