A self-propelled waterborne wave riding system includes a vessel having at least one motor and control system for navigating and propelling the vessel along a body of water. A rider section is located along the top of the vessel and includes a lower platform at the front of the vessel, an upper platform at the back of the vessel, and an elongated angled ride surface that extends between the upper and lower platforms. A pump system is provided along the vessel and includes an impeller assembly that is mechanically coupled to an inboard motor and a water pipe. Water received by the impeller is directed through the water pipe to a horizontally oriented nozzle in the lower platform which pushes the water over the ride surface. Openings in the upper platform return the used water into the body of water.
