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.

Benefits & Features
Making Your Investment Work Harder
Uses advanced predictive modeling software to select best nozzle configurations and combustion cylinder geometry, Stainless steel exhaust manifold and turbo heat shields, Closed crankcase ventilation system, Dual camshafts, Reduced aftercooler heat load for smaller heat exchanger requirements
DRIVING DOWN TOTAL COST OF OWNERSHIP
A wide range of power ratings available, No aftertreatment technology required, Fuel consumption nominal rated BSFC
COMMITTED TO SUSTAINABLE DEVELOPMENT
Modified piston bowl shape to improve combustion and reduce emissions, Uses K-factor injector to align with predictive model analysis, Better electronic injection control using crank timing vs. cam timing, EPA Marine Tier 3/IMO Tier II Emissions Compliant, Lower IMAT = Lower NOx
