A portable device for generating water current in a swimming pool is disclosed. The purpose is to provide a current against which a person can swim, for exercise or for pleasure. The invention provides an anti-cavitation plate for the suppression of whirlpool currents and the smoothing out of the bulge and waves which normally occur downstream of the propeller and preferably also includes a multi-finned enclosure housing the motor and propeller and providing for the encouragement of the development of laminar flow in the stream existing from the device for use by the swimmer.
