The invention relates to a propulsion device, in particular to an underwater propulsion device for divers (1) and swimmers comprising one or several drives (2) provided with electric motors (4) and means (3) for fixing the drives (2) to the legs or arms of the diver (1) or swimmer, wherein the electric motors (4) are provided with a sump cooling, with the electric motors (4) being arranged in waterproof housings (5) and each waterproof housing (5) only being partially filled with a cooling liquid. By arranging the drives (2) on the extremities of the diver (1) or swimmer, the flexibility and mobility are significantly increased; at the same time, the provision of a sump cooling system improves heat dissipation and thus increases the power density.
