Abstract

See full text

A marine propulsion system includes a gearbox housing that is attached to the stern of a vessel hull, a pivot casing that can pivot relative to the gearbox housing for trim/tilt and a lower unit that can pivot relative to the pivot casing to steer. The gearbox housing houses an input shaft, which is connected via a gear set to an intermediate shaft, which is connected via a bevel gear set to a transverse shaft, which extends into the pivot casing. Inside the pivot casing, a drive shaft is connected to the transverse shaft via a clutch assembly and the drive shaft extends from the pivot casing to the lower unit, where it drives a propeller shaft. The pivot casing pivots about the axis of the transverse shaft to trim/tilt and the lower unit pivots about the axis of the drive shaft to steer.
