An underwater propulsion device of the present invention comprises: a motor unit that provides propulsion power; a cover that is provided with a cavity surrounding the output shaft of the motor unit and a fixed shaft protruding behind the cavity and is fixed and coupled coaxially with the output shaft; a front rotor that is installed to surround the outer surface of the cavity of the cover and rotates according to the rotation of the output shaft; an input gear that is inserted through the fixed shaft and is connected to the front rotor to rotate; a reversing gear module that is equipped with a plurality of reversing gears engaged with an input gear to transmit rotational force; an output gear that is inserted through the fixed shaft and engages with the reversing gear to receive rotational force; a rear rotor that is connected to the output gear and rotates in the opposite direction to the front rotor; and a duct connected to the motor unit so that the front rotor and rear rotor are located inside. Accordingly, it is possible to provide an underwater propulsion device that is compact and has excellent performance with a relatively simple structure.
