Abstract

The present invention is a drive system for a boat propeller, with a motor and a reverse gearbox. For forward travel a hydrodynamic coupling is provided and for reverse travel a hydrodynamic reverse converter is provided. The coupling is operated with its maximum filling degree in the upper range of the propeller speed, but in the lower range of propeller speed with a partial filling. Thus, the hydrodynamic coupling is the single hydrodynamic power transfer unit for the entire forward speed range. In order for the boat to be able to be quickly braked down from full speed, the reverse converter is arranged to provide a high torque conversion in the reactive braking range.
