Abstract

A drive shaft supporting structure for a small boat is provided which permits simplification of a hull and for which manufacturing productivity is increased. The drive shaft supporting structure includes a shaft-supporting member for rotatably supporting a drive shaft inside of a hull, and an elongate cylindrical sleeve. The cylindrical sleeve is arranged between the shaft-supporting member and a hull opening which permits penetration of the drive shaft through the hull. The drive shaft supporting structure is configured in such a manner that a front end portion of the cylindrical sleeve is connected to the shaft-supporting member and a rear end portion of the cylindrical sleeve is connected to the hull opening.
