How Does a JET SKI Work?

Описание: Discover the engineering behind Kawasaki’s iconic personal watercraft, trademarked as Jet Ski since 1972.

These personal watercraft (PWCs) carry one to three riders seated like a motorcycle or bicycle.

Jet ski hulls are predominantly made from fiberglass or FRP composites, offering strength and durability on rough water.

A modified V hull combines deep-V cutting power at the bow with a flatter stern for enhanced stability and smooth planing.

Planing hull designs enable the craft to rise and glide across the water surface as speed increases.

Modern jet skis use 4-stroke Rotax gasoline engines, delivering up to 325 HP for record-shattering acceleration.

Inside the suction duct, a screw-shaped impeller driven by the engine draws in water and ejects a high-speed jet for powerful waterjet propulsion.

Integrated steering is achieved by pivoting the nozzle to redirect the jet, allowing for tight turns and agile maneuverability.

Adjustable trim controls the nozzle angle to raise or lower the bow, optimizing speed, stability, and handling.

Braking and reverse features use a reversing gate or hull drag for rapid slow-downs and safe docking.

Watch now to master the inner workings of waterjet propulsion, impeller mechanics, planing hulls, and all key jet ski components!
