  • Patent number: 10323911
    Abstract: The disclosed invention is a device for non-lethally stopping or slowing any water jet propelled craft, such as a common personal watercraft (PWC), by disrupting the water suction and thereby reducing the generated thrust. Most PWCs have an inboard engine that is coupled to a water jet pump which uses an impeller to generate thrust. This invention is ingested by the PWC intake to either clog the intake gate (or screen) or fill critical volume in any portion of the jet pump (such as the intake, impeller, stator, or pressure nozzle). In any case, water flow through the jet drive is significantly reduced which reduces the vessel's thrust. PWCs depend on adequate water flow through the jet pump to generate the thrust required for propulsion and steerage, and to provide engine cooling. Since this invention is designed to interrupt water flow, the result is reduced speed, steerage, and/or engine overheating.
