Cat C18 ACERT High Performance Propulsion Engine (Tier 3)

The C18 ACERT marine propulsion engine has high performance commercial application ratings of 814-1015 mhp (803-1001 bhp) at 2100-2300 rpm that meet U.S. EPA Tier 3, IMO II, and EU Stage IIIA emissions regulations. In addition to meeting the stricter EPA Tier 3 emissions, this engine now offers a fresh water aftercooled option for the commercial propulsion and auxiliary engines and genset packages. From fishing to offshore and everything in between, you can be confident that we have the solution to fit your needs.

Separate circuit aftercooling system

The primary advantage of the separate circuit aftercooling system (SCAC) is that no sea water circulates through the aftercooler

Emissions

EPA Tier 3 compliant, IMO II and EU IWW compliant

Cooling system

Heat exchanger and Keel cooled options for all ratings

Turbo Configurations

Single turbo configurations for all ratings

Competitive size and weight

Marine Certifications

All major MCS type approvals available from factory
