Inspiration For electric motors constructed ships have in the rarest cases, a shaft drive system, because the powertrain require much space and the installation of the shaft system is complex. However, the modification of an existing system is always a challenge that can be implemented with a shaft drive of Krautler. Whether sail or motor boat, whether daysailer or passenger ship, the possibilities are diverse and the demands on the systems highly. Krautler has the right solution for our boat. The luxury of being able to move almost silently is the most beautiful experience of navigating with an electrically powered boat. By the selection of the gearbox the efficiency and smooth running are very important. Only with the use of gears which match these criteria, it is possible to offer innovative drive solutions for your application. By a new boat design, the shaft and propeller are dimensioned according to the characteristics of the electric drive. For this application a Krautler shaft drive (without a gearbox) fits perfectly. For an existing shaft system with propeller, the shaft drive with a gearbox can be adjusted to the existing system. The future drive technology belongs to the electric motor. Besides the higher efficiency of an electric motor compared to a gasoline engine, the electric motor scores with its zero emissions. An additional advantage is that in comparison to the gasoline engine the electric motor is more simple structure and the resulting reduced amount of wear parts.
