Abstract
A V bottom hull watercraft powered by a pair of jet propulsion units that are supported for pivotal movement about horizontally disposed pivot axes and rotary movement about a longitudinal pivot axis to rotate the water inlet openings and elevate them from a downwardly facing normal operating position and an upwardly facing service position. The water inlet openings are disposed so that they extend parallel to the sides of the V bottom. Steering nozzles are supported for pivotal movement at the discharge ends of the jet propulsion units and pivot about vertically extending axes that are not perpendicular to the water inlet openings so that no vertical thrust will be exerted on the watercraft hull when the steering nozzles are pivoted to effect steering.
