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, larger 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 poss i- ble. The high - quality electric controller works almost without loss and protects your valuable battery pack against too deep discharge. With the mode rn controller we have the po s- sibility to adapt the drive system optimally to your ship.
