3512C Tier 3 Marine Propulsion Engine

Overview

The 3512C High Displacement marine engines are now available in a wide range of ratings that meet EPA Marine Tier 3 and IMO II regulations without any additional aftertreatment. These new propulsion, auxiliary, and DEP engines, designed and built from the current 3512C and 3516C platforms, 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 EPA Tier 3 compliance.
