How does waterjet propulsion work? Steer and reverse in 3D
A waterjet propels a boat by taking in water beneath the hull and accelerating it toward the stern. An enclosed impeller drives the flow through fixed guide vanes and a nozzle. Turning the nozzle redirects the jet for steering; lowering a reversing bucket sends the discharge forward without reversing the impeller. Try both changes in this cutaway model.
