A jet propulsion unit for a marine vessel that comprises a diffuser/confusor; a steering control nozzle assembly; and a radius. The radius is introduced at a transition point between the diffuser/confusor and steering control nozzle assembly so that the diffuser/confusor can control a shape of water flow exiting the propulsion unit and can control corresponding acceleration over a large pressure differential presented by a wide range of vessel speeds, maneuvers and sea conditions. |
