ABSTRACT:
Several embodiments of jet propelled watercraft that incorporate an arrangement for hydraulically pivoting the jet propulsion unit between a normal position and a raised position and for rotating the water inlet portion of the jet propulsion unit from a downwardly facing direction to an upwardly facing service position. Hydraulic motors are employed for achieving both motions and are actuated through a common circuit for achieving sequential movement. In one embodiment, the rotary hydraulic motor is formed integrally within portions of the housing of the jet propulsion unit to provide a compact assembly.
