Abstract

Several embodiments of jet propelled watercraft including steering rudders pivotally supported by the steering nozzle of the jet propulsion unit for providing a steering affect at low speeds and when coasting. The steering rudder is selectively moveable between its steering position and non-steering position so as to permit unincumbered high speed operation. An arrangement is incorporated that permits the rudder to pivot automatically from its steering position to an out of the way position when an underwater obstacle is struck.
