Overview

The C18 ACERT marine propulsion engine has commercial application ratings of 475-725 mhp (469-715 bhp) at 1800-2100 rpm that meet U.S. EPA Tier 3, IMO II, and EU IW 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.
