PROBLEM TO BE SOLVED: To effectively transmit driving force of an outboard motor to a hull without waste at the time of propulsion in connecting structure between the hull and the outboard motor, and to prevent vibration of the motor from being transmitted to the hull. ;SOLUTION: In this connecting structure via an elastic mount for an outboard motor composed of a hull bracket, and an outboard motor main body supported to the bracket freely to turn laterally around a swivel shaft, and connected with the bracket provided in the swivel shaft and the motor main body via the elastic mount, bolt members projected to an outboard motor main body side is arranged in left and right sides of the upper part of the swivel shaft, an elastic body 103 is arranged in the outer circumference of the bolt member, the left and right parts of the outboard motor main body are connected to the bolt members via the elastic body 103, and the cross section of an elastic body part constituting the elastic mount is formed into a noncircular shape of which the traverse dimension L2 to its longitudinal dimension L1 is made to be L1L2 in the view from a direction applied with thrust of the outboard motor.;COPYRIGHT: (C)1999,JPO
