C32

Bore: 5.71 in / 145 mm
Stroke: 6.38 in / 162 mm
Displacement: 1959 in³ / 32.1 l

The C32 marine propulsion engine is available at ratings that meet EPA Tier 3, EPA Tier 4, and IMO II/III, and EU Stage 5 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 has several 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 marine engine is supported by the extensive Cat global dealer network and standard warranty.
