What propulsion type uses an aircraft-type propeller in watercraft?

The propulsion type that utilizes an aircraft-type propeller in watercraft is known as Air Thrust. This system takes advantage of the principles of aerodynamics and hydrodynamics to propel the vessel through water by generating lift similar to how an aircraft operates. The concept involves creating a high-speed thrust that effectively pushes the watercraft forward.

In contrast, the other options refer to different propulsion methods. Jet Drive uses a jet of water expelled from the back of the boat to create thrust, which is quite different from using a propeller. Stern Drive combines an inboard engine and an outboard drive leg but does not specifically use an aircraft-style propeller. Similarly, Inboard Drive utilizes propellers connected to an engine located inside the vessel, again not resembling the aircraft-style propeller systems. Therefore, the primary distinction of Air Thrust lies in its reliance on the principles of propulsion akin to an aircraft, which sets it apart from the other types mentioned.
