摘要

The boat drive has a propeller shaft, and three motor drive units with a perpendicularly standing propeller shaft, which is seen in a top view in a geometrical triangle e.g. square or polygon, are arranged below or lateral to a floating body. The upper limit of the drive is formed for the propeller blades of the water surface.
