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.

Features may include:

• 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

• A wide range of power ratings available, no aftertreatment technology required, fuel consumption nominal rated BSFC

• 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

• Electronic governing (A4 ECU), instrument panel shipped loose with color marine power display (MPD), cold mode start strategy, programmable low idle
