The vibrator system of this invention provides conversion of rotary motion to an unidirectional motion and may be used to propel watervessels. The vibrator system involves a rotating vibrator unit which bears large and small rotating eccentric weights. A gear arrangement provides synchronized rotation of the weights which results in a net unidirectional force. In a second embodiment, two vibrator units are mounted on a single frame and are rotated in synchrony.
