The electric motor rotor (10R) is coupled to the propeller shaft (2) by a spherical toothed coupling (8). The motor has hydrodynamic or hydrostatic roller bearings (14) with runners completed by two hydrodynamic or hydrostatic runner stops (15). The motor is fixed in a nacelle (20) by a coupling (9). The ship propulsion unit in a suspended nacelle includes: (a) a nacelle (20) suspended from the ships hull; an asynchronous squirrel cage wound pole permanent magnet electric motor with rotor (10R), stator (10S) and two bearings (14) between them, the motor is placed in the nacelle, and; a propeller (1) mounted on a substantially horizontal shaft (2)
