Abstract

A marine jet drive apparatus includes a power trim unit coupled to a jet deflector for remote trim positioning of the jet and for controlling steering deflection of the jet to either side. An auxiliary rudder also coupled to the jet deflector to vary the effectiveness of the auxiliary rudder with the trim positioning. The main jet deflector is a tubular extension of the jet nozzle and is mounted for trim positioning. The main jet deflector is a tubular extension of the jet nozzle and is mounted for trim rotation about a transverse axis by a gimbal ring. A powered trim control link is connected to the ring for setting of the jet with respect to the horizontal. The jet deflector is pivotally mounted within the gimbal ring to create a vertical steering axis for angular positioning of the jet deflector through the normal 40 DEG to 50 DEG for conventional type steering. The rudder has an upper portion projecting between a pair of depending walls of the jet deflector and with the opposite sides slidably engaging the opposing portions of the walls. As the trim position of the jet deflector changes, the sliding coupling automatically moves with respect to the pivot axis of the auxiliary rudder and varies the effective center of rotation of the coupling with respect to the axis of the deflector and the rudder axis.
