Abstract: Pod drive which can be fitted to a vessel and which is provided with an electric motor which drives a propeller shaft which is likewise provided in the housing of the pod drive and is connected to a propeller which is situated outside the latter. It is proposed to use a fast-rotating electric motor in combination with a reduction gearing for driving the propeller shaft. The mounting of the propeller shaft is made particularly stable by mounting it on both sides of the electric motor. The reduction gearing may include a planetary system. The electric motor may be fitted next to the hollow propeller shaft. In this case, several electric motors can be arranged around the central propeller shaft. It is also possible to make the rotor of the electric motor hollow and to fit the propeller shaft inside the latter.
