The present disclosure relates to a ship's propulsion unit such as a ship's azimuthing propulsion unit. The propulsion unit can include at least one supporting metal sheet arranged between an support section of a shell structure of the propulsion unit and an cylindrical outer surface of a cylindrical section of a motor housing section of the shell structure for providing additional support for the motor housing section of the shell structure at the shell structure of the support section.

The invention relates to a method for mounting a prefabricated deck (31) on a boat deck (36), said prefabricated deck comprising one or more deck elements (02) and the method comprising the following steps: setting a target height profile (11) for the upper face of the prefabricated deck (01); generating a mounting height profile (22), which is spaced apart from, in particular spatially parallel to, the target height profile (11) in the direction of the boat deck (36) by the thickness of the deck element (02); measuring the upper face of the boat deck (36) as the actual height profile (21); determining the height difference (23) between the actual height profile (21) and the mounting height profile (22); producing at least one leveling means (38) per deck element (02), said leveling means having a material thickness that corresponds to the height difference (23); mounting, in particular gluing, the leveling means (38) and the deck element (02) to the boat deck (36), the surface of the mounted prefabricated deck (31) substantially corresponding to the target height profile (11).
