A drive unit ( 1 ) with a steering motor and a propulsion motor, a first ( 2 ) of the two motors having a hollow drive shaft ( 5 ) through which a drive shaft ( 14 ) of a second motor ( 10 ) passes. Winding heads ( 7 ) of the first motor are positioned radially inside winding heads ( 15 ) of the second motor and overlap with them in axial direction, to save structural space in the axial direction. A stator ( 11 ) of the second motor is not solid but hollow with a port or bell shape. A rotor ( 12 ) of the second motor is in contact with the associated drive shaft not over its entire axial length, but only at a first end ( 13 ) which forms the bottom of the pot. This design forms a hollow space in which elements of the first motor can be accommodated at least partially. Parts of the two electric motors ( 2, 10 ) overlap in axial direction, where further axial structural space is advantageously saved.
