It is provided for to arrange, at least in the region between the arms of the propeller brackets, a sectioned arcuate guide surface. This guide surface possesses a mean camber line converging backwardly towards the propeller shaft and the outlet edge has a distance to the propeller shaft amounting to between 70 and 130% of the propeller radius. This arcuate section of the guide surface is connected, on the side facing the ship's hull, to an approximately horizontal radial part.
