Outboard engine body is mounted via a swivel shaft to a stern bracket. Angle sensor, provided on the stern bracket, includes a contact having a maximum operating angle set to be not greater than half of a maximum steered angle of the engine body, and it outputs detection information indicative of an operating angle of the contact. Curved member is provided on the engine body and normally held in engagement with the contact, and it has a continuously varying radius of curvature from the central axis of the swivel shaft, so that the contact varies in operating angle while sliding along a curved outer peripheral surface of the curved member in response to steering operation. Thus, a steered angle is determined on the basis of the detection information from the angle sensor.
