ABSTRACT:
An inboard-outboard drive is taught having an upper, approximately horizontal input shaft; an output shaft substantially parallel thereto for driving a propeller; and a vertically-oriented intermediate shaft coupled to the other shafts by suitable gearing. The upper and lower shafts are journaled in upper and lower housings, respectively. A tubular member disposed coaxially with the intermediate shaft couples the upper and lower housings, allowing the lower housing to rotate with respect to the upper housing. The tubular member is associated with a steering member opposite sides of which are coupled to ones of a pair of hydraulic cylinders disposed within the upper housing. In one embodiment the steering member comprises a pinion which is rotated by rack gears coupled to the hydraulic cylinders and adapted to slide back and forth in ways formed in the upper housing. In another embodiment, the steering member is a bellcrank keyed to the tubular member and coupled to the hydraulic cylinders by linkage arms.
