The efficiency of a ship propulsion system depends on the shaft speed and the correct selection of the used propeller. Because of the superior torque curve of an electric motor compared to a gasoline engine, large r 2 - and 3 - blade propeller can be used at low shaft speed. Because of this principle, a very high thrust is developed even with small drives. Both the AC and the GP engine are available with either a fixed or folding propeller. Kräutler AC drives are also completely maintenance - free .
With the comfortable single - lever controller a variable speed control in forward and reverse drive is possible. The high - quality electric contro l- ler works almost without loss and protects your valuable battery pack against too deep discharge. With the modern controller we have the possibility to adapt the drive system optimally to your ship.
