Abstract: An outboard propulsion system comprising a support for attachment to the deck of a vessel to which is bolted a prime mover with its drive shaft in a horizontal position transversely of the vessel, a propulsion assembly supported by the support in suspension outboard of the vessel for arcuate movement about a horizontal axis parallel to the axis of the drive shaft, the propulsion assembly comprising an upper gear box, an input shaft journaled in the gear box on an axis coinciding with said horizontal axis, a steering column connected at its upper end to the gear box for rotation about an axis at right angles to the axis of the input shaft, a lower gear box fixed to the lower end of the steering column within which is journaled a propeller shaft, gears in the lower gear box drivably connecting the propeller shaft to the transmission shaft, a hydraulic elevating cylinder for effecting arcuate movement of the propulsion assembly in a vertical plane about the axis of the input shaft, a hydraulic clutch for operabl

Abstract: An outboard motor system for propelling a vessel comprising a power plant stationarily fixed to the vessel with its drive shaft in the horizontal athwartship position, a propeller assembly comprising a propeller and a kinematic train for driving the same mounted to the vessel for rotation about a horizontal axis parallel to the axis of the drive shaft and for vertical movement relative to the drive shaft, the kinematic train including an input shaft, the axis of which coincides with the axis of rotation of the propeller assembly and is parallel to the drive shaft, pulleys fixed to the respective shafts and a band entrained about the pulleys.
