Vertically adjustable stern drive for watercraft |
摘要 |
A marine stern drive includes a tilt/trim and lift adjustment mechanism which raises and lowers the drive while maintaining an established trim angle. The adjustment mechanism includes a parallelogram linkage system. An upper lever of the linkage system is defined in part by a pair of tilt and trim actuators which vary the length of the upper linkage to adjust the trim position of the stern drive and for tilt up. A lower lever of the linkage system is defined between two flexible couplings of a propulsion drive train. One of the flexible couplings is coupled to a lower drive unit of the stern drive which permits the lower lever to rotate without changing the trim angle of the lower drive unit.
