Jetboat - Wikipedia

A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.

The jet is further disadvantaged because its entire powertrain is mounted within the boat hull, so part of the noise of a jet drive is the flow of water through the pump and the sound of cavitation on the low-pressure side of the impeller. The jet also runs at much higher rpm, and this higher-frequency sound is more irritating to the human brain.
