An improved hydraulic engine for boats and the like is provided which preferably includes a rearwardly facing concave impingement surface, along with nozzle apparatus for directing a stream of pressurized water against the impingement surface in order to move the boat forwardly through the water. An oppositely oriented, concave, flow-directional surface is disposed in partial opposition to the impingement surface for deflecting non-pressurized water against the impingement surface as the boat moves through the water. The below water portion of the engine is housed in an open-ended casing, and can be rectangular or circular configuration.
