Abstract
A marine jet propulsion system has a jet pump, a venturi connected to the jet pump, and a steering nozzle rotationally mounted relative to the venturi about a first axis. The steering nozzle has a central longitudinal axis. The first axis intersects the central longitudinal axis. A first link has a first end rotationally mounted relative to the venturi about a second axis. The first link has a second end disposed generally rearwardly from the first end of the first link. A second link has a first end rotationally mounted to the first link about a third axis and a second end rotationally mounted to the steering nozzle about a fourth axis. The third axis intersects the second end of the first link. A steering arm is connected to the first link. The axes are generally parallel to each other. A watercraft having the jet propulsion system is also disclosed.
