摘要： A water jet apparatus mounted to a horizontal hull section and having a shift and steering control assembly which penetrates a hole in that hull section. The shift and steering control assembly has a modular lever and shaft subassembly which is installed in the inlet housing, before the inlet housing is installed in the hull. The modular lever and shaft assembly includes a shift and steering control housing mounted to the inlet housing and having respective bores for housing shift and steering shafts. Upper shift and steering levers are coupled to the upper ends of the shift and steering shafts respectively, while lower shift and steering levers are coupled to the lower ends of the shift and steering shafts respectively. Respective control cables are attached to the upper levers inside the hull; respective control rods for operating a steering nozzle and a reverse gate are attached to the lower levers outside the hull.

摘要： A self-deploying rudder assembly for use with a water craft including an exhaust port having a exhaust stream includes a mounting assembly and a pivoting rudder blade assembly. The pivoting rudder blade assembly typically includes a thrust plate attached to one end of a rudder shaft and a rudder blade attached to the other end of the rudder shaft. When the selected thrust level is above the preselected thrust level, the thrust plate is moved out of the exhaust stream and the rudder blade is thereby moved from a deployed, operational position to a stored position.

摘要： A watercraft of the jet propulsion type comprising a steering mechanism, a throttle control mechanism, a thrust mechanism, a throttle regulator and a controlled thrust steering system. The steering mechanism has a straight-ahead position. The steering mechanism is able to rotate in a clockwise direction from the straight-ahead position to a clockwise position and in a counter-clockwise direction from the straight-ahead position to a counter-clockwise position. The throttle control mechanism is biased toward an idle position. The thrust mechanism provides jet propulsion thrust for the watercraft. The throttle regulator regulates thrust provided by the thrust mechanism. The controlled thrust steering system causes the throttle regulator to increase thrust upon the steering mechanism rotating from the straight-ahead position to the clockwise position or the counter-clockwise position. The controlled thrust steering system also causes the throttle regulator to decrease thrust upon the steering mechanism rotating from the clockwise position or the counter-clockwise position to the straight-ahead position.
