Abstract

The invention relates to a drive for a watercraft comprising a) a rotating unit provided with a propeller; b) an electric motor provided with a coaxial arrangement of rotors and stators and a radially oriented magnetic field, said rotor being arranged on the outside of the body of the watercraft and being non-rotationally connected to the propeller; c) an air gap between the rotor and the stator is flooded and the rotor and/or the stator are encapsulated in a water-tight manner and d) when seen in the axial direction, water-lubricated friction bearings that at least radially support said rotating unit are arranged on both sides of the air gap.
