A personal watercraft’s propulsion system, unlike traditional propeller-driven boats, relies on an impeller housed within a duct to create a powerful jet of water for thrust. This system comprises various components, including the impeller, wear ring, stator, intake grate, and steering nozzle, all working together to generate motion. For example, the impeller spins rapidly to draw water in and then expel it with force, while the wear ring maintains efficient flow and the steering nozzle directs the jet stream to control the vessel’s direction.
This method of propulsion offers distinct advantages, such as improved maneuverability in shallow waters and a reduced risk of propeller strikes. Historically, this technology saw early adoption in smaller recreational craft and has since evolved to find application in larger vessels, demonstrating its effectiveness and versatility across various marine environments. Its compact design also contributes to greater space efficiency within the boat.
