Overview

The 3516C High Displacement marine engines are now available in a wide range of ratings that meet IMO II emissions regulations. This new propulsion, auxiliary, and DEP engines, designed and built from the current 3516C platform, have minimal dimensional and weight changes in comparison. Owning and operating costs are also very similar. For the specific fuel consumption of each rating please refer to the performance data. New features include stainless steel exhaust heat shields, closed crankcase ventilation system, and IMO II emissions compliance.
