pump-jet
Enclosed watercraft propulsion
A pump-jet is a marine propulsion system that draws water through an intake, accelerates it with an impeller, and expels it through a nozzle to generate thrust.
Unlike exposed propellers, the mechanism is enclosed within the hull, reducing drag and protecting against debris.
Pump-jets power personal watercraft, ferries, and military vessels where maneuverability or stealth matters: The submarine's pump-jet made it nearly silent.
