ABSTRACT:
A mounting arrangement is provided for mounting an outboard drive for movement between a tilted down position through trim adjusted positions to a tilted up out of the water position. The arrangement includes a quadrilateral linkage system and a hydraulic motor device which simultaneously lifts and tilts a motor relative to an associated watercraft. The invention allows the links employed in the linkage system to be constructed so that the cross-sectional areas along their lengthwise axes are greatest along their central regions, whereat they are pivotally connected together, and decreases towards each of their ends, thereby minimizing the weight of the arrangement.
