ABSTRACT:
A weedless system has been developed for personal watercraft which obtain their power by using jet propelled water pumps. The unique weedless system has a number of elements which help to reduce weed congestion in the jet pump. Firstly, a plurality of downwardly directed grates, which terminate at the head of the ride shoe, are used such that weeds striking such grates will tend to slide off the grates rather than become embroiled around them. In addition, between the venturi and the steering nozzle there is located a butterfly valve which can be manually closed or opened by the operator. Closure of the butterfly valve creates a rotating movement of the water within the jet pump to provoke shaking, cutting and dislodging of weeds that go through the great barrier. The weeds then pass out through the water inlet back through a weed outlet passage or become pulverized such that they will pass safely past the jet pump when the valve is reopened and the boat regains normal efficiency.
