ABSTRACT:
A marine speedometer for mounting to the exterior transom of a marine vessel includes a housing mounted to the transom flush with the bottom surface of the hull. A paddlewheel affixed to the housing has an outer periphery which extends no further than the bottom surface of the hull of the marine vessel. A portion of the housing adjacent to the bottom surface of the hull is shaped to direct a flow of water passing by the transom upwards into the paddlewheel to rotate the paddlewheel.
