The 3516E marine propulsion engine is now available in a wide range of ratings that meet U.S. EPA Tier 4 Final and IMO III marine emissions regulations. As the commercial marine industry adjusts their operations to meet EPA Tier 4 and IMO III emissions standards, Caterpillar Marine has introduced a solution built to maximize performance while meeting regulations. Caterpillar’s combination of a fuel-efficiency-optimized engine and a selective catalytic reduction (SCR) aftertreatment system is a solution that not only reduces NOx emissions, but can also lower a customer’s owning and operating costs in the process.

The 3516C propulsion engine is available with a wide range of ratings that meet EPA Tier 3 and IMO II regulations without any additional aftertreatment. These engines provide efficient operation with electronic governing, cold mode start strategy, and programmable low idle to minimize fuel consumption. The 3516C engine also incorporates a closed crankcase ventilation system to lower emissions.

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.

The Cat 3512C marine propulsion engine makes your investment work harder. Through a wide range of available power ratings (including High Displacement ratings), no required aftertreatment technology, and nominal rated BSFC fuel consumption – it will drive down your total cost of ownership. With a redesigned piston bowl shape to improve combustion, and improved fuel delivery, this engine is IMO II emissions compliant and committed to sustainable environmental development. Single-source support, the Caterpillar warranty, and industry-leading one-year warranty on parts make the 3512C a fully integrated marine power solution.

The 3508C marine propulsion engine meets IMO II emissions regulation and delivers more power with lower emissions for your marine propulsion needs. Additionally, the 3508C provides outstanding fuel efficiency and lube oil consumption. Standard or reverse rotation options are available as well as worldwide parts and service. The 3500 engine platform is a streamlined and proven design that provides industry-leading reliability & durability.
