A rubber band motor which utilizes a long length of band material in a relatively short toy housing and which enables rapid winding of the band, comprising a first rubber band extending between a rotatable output member and a first gear and a second rubber band extending between a second gear and a stationary bracket. The two gears are normally engaged so that the rubber bands are connected in series to drive the rotatable output member. A winding gear moves into engagement with the first and second gears while separating them from each other when the rubber bands are being wound, so that the winding gear winds both rubber bands simultaneously, i.e., in parallel. When winding forces are no longer applied to the winding gear, it disengages from the first and second gears and allows them to re-engage so that they unwind in series. The motor is useful in a water toy with a flapping tail that propels it through the water while carrying a figure representing a man whose arms engage a pair of fins on the vehicle.
