ABSTRACT:
A nozzle drive propulsion assembly for use with a marine craft and incorporating an annularly configured nozzle disposed in surrounding relation to a propeller collectively mounted exteriorly of the marine craft and preferably, at least partially, within an elongate recessed channel formed in the hull. A strut assembly is connected to the nozzle in transverse relation to a trailing open end thereof, downstream of the propeller and in at least partially supporting relation to the propeller. The nozzle includes a collection assembly including a water collecting chamber incorporating a pitot-type structure for directing water into the collecting chamber and along a path of fluid flow in the strut assembly to a thrust member mounted on the strut assembly. A rudder assembly and a deflector structure are secured to an exterior of the nozzle and function to determine the craft's direction of travel.
