Abstract: An apparatus for mounting an outboard motor on the transom of a boat so that the motor can be raised and lowered on the transom. The apparatus comprises two slidably connected brackets, one for securing to the transom of the boat and one for carrying the outboard motor, and a hydraulic actuating cylinder connected between the two brackets for moving the motor mounting bracket along a vertical line relative to the bracket secured to the transom. A reversible hydraulic pump is provided for operating the hydraulic actuating cylinder.

Abstract: An improved chain speed reducer assembly comprising a drive shaft supported at one end by a first bearing block and by a second bearing block at the other end. Each of the bearing blocks has a shaft supporting bore that is axially displaced a predetermined offset distance from the central axis of the bearing block, and each of the bearing blocks is supported by a gear box frame so as to be selectively rotatable about the central axis of each bearing block. Attaching bolt connectors permit the bearing blocks to be secured at selected angular dispositions. This permits selective canting of the drive shaft, and when coupled with other similarly supported driven shafts supporting plural sprockets, separate strands of roller chains can be adjusted independently via the eccentric movement of the bearing block supporting bores upon selective rotation of the bearing blocks.
