ABSTRACT:
A jet drive pump is secured to the boat transom and includes a gimbal ring pivoted on a horizontal trim axis and a steering nozzle is pivotally mounted on a vertical pivot axis within the gimbal ring for steering. A trim linkage is connected to position the gimbal ring for trimming of the nozzle. A reversing gate is pivotally mounted on the same trim axis and connected by a mechanical coupling linkage with swivel and pivoting joints to the gimbal ring. The linkage has an axially sliding shift shaft in a rotatable shift lever for rotation about an axis perpendicular to the trim axis. Shaft rotation actuates the coupling linkage to pivot and place the gate in shift position. Trim movement of the ring through the coupling linkage positions the gate and with the sliding shaft moving to hold the present gate position. The shaft extends through a rotatable steering tube. A flexible bearing end of the tube permits limited shaft flexing.
