Summary

Neander accomplished what was announced in 2013 during the Aachen conference of that year: Neander is producing its new two cylinder turbodiesel outboard engine with dual crankshaft technology for the commercial marine market in the most important 40 to 60 hp outboard segment.

Together with Selva, Italy, and many renowned engine component manufacturers like Bosch, BorgWarner, Alfing, Schaeffler and others and the engine assembly experts of Steyr Motors, Austria, a unique and innovative powertrain was introduced to the market in 2017 and is being sold since then successfully. An international engineering and manufacturing team with the assistance also from FEV achieved to develop and industrialize a new two cylinder marine engine powertrain which sets a new standard in lowest vibration operation, low fuel consumption and durability and reliability in that market place. The minimalistic and lean approach to new product development definitely sets a benchmark towards the industry.

With Yanmar, one of the largest diesel engine manufacturers of the world, the sales and distribution globally could be secured through a mutual partnership.

This paper outlines the basic technologies and designs of the engine, technological achievements and the unique approaches to develop such an engine on a resource level unknown so far to the industry.
