TRIM AND REVERSE SYSTEMS FOR A JET PROPULSION WATERCRAFT

摘要

Systems for controlling the trim of the nozzle of a jet propulsion watercraft as well as the operation of the reverse gate of such a watercraft are provided. Firstly a commonly actuated trim and reverse system is provided in which both the trim angle of the nozzle and the orientation of the reverse gate are electronically controlled through a single actuator. Secondly, an electronically assisted reverse gate system is provided where the operating conditions of the watercraft are taken into consideration into the evaluation of the orientation to be given to the reverse gate. Finally, an automatic trim control system, taking into account the steering angle to automatically control the trim angle, is further provided.
