CAT C32 ACERT MARINE PROPULSION ENGINE (EPA TIER 3)
The C32 ACERT marine propulsion engine is available at ratings that meet both EPA Tier 3 and IMO II emissions regulations. It has a separate circuit aftercooling system (SCAC) for A through C ratings and a seawater aftercooling system (SWAC) for D and E ratings. The C32 ACERT has seven ratings with Wide Operating Speed Range (WOSR) and extended oil change intervals. Other benefits include proven engine operating history and performance iron with thousands of validation testing hours for quality and durability. The C32 ACERT marine engine is supported by the extensive Cat global dealer network and Caterpillar’s 60 month standard warranty.
