First developed by Archimedes, the screw drive was designed to pump water to a higher elevation. The Great Britain was the first ocean liner to utilize a screw design although the British Navy had built a ship using this technique. They take a portion of a screw and use it as a method of propelling a water craft, hence, the name propellor. Technically a motor is electric and not internal combustion, but common usage is different.
Short answer is: any engine with a prop.
