Abstract
A steering and reversing system for a marine jet propulsion unit having a stationary nozzle (3) for discharging a water jet rearwardly from the unit comprises a pair of steering and reversing members (4, 5) which are mounted side by side at the rear end of the nozzle and individually pivotable in opposite directions about upright axes (7) from a non-deflecting position to first and second deflecting positions. In the non-deflecting position, the steering and reversing members (4, 5) form a rearwardly directed extension of the nozzle, while in the first deflecting position each member diverts a portion of the water jet laterally outwardly by means of its front section (4a, 5a) and in the second deflecting position each member deflects a portion of the water jet downwardly and forwardly by means of scoop-like members at its rear section (4b, 5b).
