Abstract: A marine pod breakaway connection includes a breakaway connector connecting ends of a vertical shaft in an upper housing section and a vertical shaft in a lower housing section. The breakaway connector is configured to yield or fracture to allow the vertical shafts to separate during a breakaway condition when the lower housing section separates from the upper housing section. The breakaway connection further includes disconnect fittings having upper section in the upper and lower portions in the upper and lower housing sections, respectively, the engage and open when the housing sections are assembled to allow fluid flow, and close when the housing sections are separated to substantially prevent leakage of oil from the housing sections.

Abstract: A hull seal assembly securing a drive unit within an opening in a boat hull may include a lower housing section, an upper housing section and an intermediate housing section of the drive unit, with the intermediate housing section having an outwardly extending retention portion. The hull seal assembly further includes a hull support ring mounted to a bottom of the boat hull and surrounding the opening and a clamp ring installed around the drive unit. with the hull support ring having a downwardly facing support ring surface; and fastened to the hull support ring and having an upwardly facing clamp ring surface. The outwardly extending retention portion may be disposed between a downwardly facing support ring surface and an upwardly facing clamp ring surface to retain the outwardly extending retention portion of the drive unit within the hull support ring.

Abstract: A transmission system includes a housing, an input shaft, a first bearing, a second bearing, and a hydraulic pump. The housing defines a hydraulic circuit therein. The input shaft rotatably disposed within the housing. The first bearing and the second bearing are mounted on the input shaft, and are spaced apart from each other along a longitudinal axis of the input shaft. The hydraulic pump is disposed between the first bearing and the second bearing. The hydraulic pump is further disposed in fluid communication with the hydraulic circuit.
