ABSTRACT OF THE DISCLOSURE A jet propelled boat has a hull in which is located a passenger compartment, and a transom at the stern of the boat. The boat has a propulsion unit mounted on the rear of the transom, and the propulsion unit comprises an internal combustion engine having a vertical output shaft extending below the engine, the engine having an exhaust passage. An impeller housing is rigidly secured to the engine beneath the same with a water intake passage adjacent the bottom of the hull and a water discharge passage extending rearwardly from the transom at a vertical height approximately that o-f the bottom of the transom. An impeller in the impeller housing is mounted for rotation about a vertical axis and has a vertical drive shaft connected to the output shaft of the engine. A housing is secured to the underside of the propulsion unit, with the housing having a water discharge compartment directed to the front of the boat and an adjacent gas discharge compartment and the gas discharge compartment has side openings. Movable deflecting means for deflecting the water issues from the water discharge passage into the water discharge compartment when it is desired to have the boat move rearwardly. The water passes laterally out of the side openings, and means connect the gas discharge compartment to the exhaust passage of the engine so that the exhaust gas passes out through the side openings.
