ABSTRACT The invention relates to an electromotive drive device for a floatable device, preferably a float tube, with a drive, which includes an electric motor, which is operable by means of a separate power supply module with an energy accumulator, an electronic open-loop/closed-loop control unit and a remote control, wherein the electric motor is disposed within a housing and outside the housing is connected to a drive propeller, which at least partially is surrounded by a protective device, which is connected to the housing via connecting supports, wherein the housing consists of an upper housing part and a lower housing part, which are connected to each other by means of at least one releasable connection, wherein the housing includes a bow in an enveloping elliptical embodiment, the end thereof transitioning into an essentially circular diameter, the relative dimensions thereof as a sum being larger than an end of the housing with a projection opposite the bow, and in that the housing in the lateral area behind the diameter is provided with intake openings for cooling water to flow in when operating the drive, which cooling water, after sectioned contact with the exterior termination of the electric motor while assisting the driving, can exit again via outlet openings, which are provided in the connecting supports. Likewise, the invention relates to a method for operating an electromotive drive device, which includes an electronic open-loop/closed-loop control unit with an information processing unit, which, should the primary or final energy input drop, with sufficient safety for the drive ensures energetic use of the energy provided by the power supply module by reducing power while considering a travelled distance or travel time of the floatable device. 27 Date Recue/Date Received 2020-11-19
