This invention is a paddlewheel apparatus having an epicyclic gear train in a rotatable holder at an end of a plurality of cantilevered paddles. The paddles are maintained substantially vertical throughout the rotation of the holder and they are completely unobstructed by any other part of the apparatus in all phases of operation. A housing which extends over the holder and the paddles is open at the bottom to pass the downwardly hanging paddles into the water.
