Abstract: Conversion of a stand up paddle (SUP) board or similar personal watercraft to enable it to be powered by a battery and an electric motor and propeller apparatus requires a practical and performance oriented configuration to be successful. This patent describes an optimal configuration that utilizes a vertical hollow protrusion through the stand up paddle board that supports the propulsion system and is comprised of two assemblies; a motor and propeller assembly, and a battery and control assembly.

This is accomplished by locating the hollow protrusion and equipment associated with the motorized system relatively close to, and forward of the rider.
