Since 2007 there was no offering anymore of diesel outboards in the important power segment around 50 hp in the commercial outboard market. Neander Motors AG is closing this gap with a newly developed two-cylinder twin diesel outboard engine with a new and state-of-the art design, the Dtorque 111. The application of a counter rotating twin crankshaft system together with advances in balancing techniques create an engine unique in NVH and operator friendliness.

The 50-hp outboard market segment for commercial boat applications was identified to be optimal for introducing vibration-free und low noise emitting diesel engines with their thermodynamic advantages. The design with two counter-rotating crankshafts creates the key basis. Not only mass forces in cylinder axis are dramatically...
