Two propeller shafts are disposed coaxially one within another. A collar of the inner propeller shaft grips into the hollow outer propeller and supports the inner shaft axially over axial friction bearing elements. The axial friction bearing elements are surrounded by a shaft connecting piece, which is divided in the axial direction and at least one half of which can be removed radially, in order to create access to the axial friction bearing elements. By way of the axial friction bearing elements, axial forces of the inner propeller shaft reach the hollow outer propeller shaft and, from the latter, by way of further axial friction bearing elements, further reach a bearing housing, which is preferably also divided in the longitudinal direction.
