Overview

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.

Emissions

IMO II/EPA Tier 3 Compliant Ratings

Separate Circuit Aftercooling System (SCAC) for A-C ratings

No seawater circulating through the aftercooling system to prevent corrosion.

Seven Ratings with Wide Operating Speed Range (WOSR)

Full power & torque are available for a broader operating speed range. For example: With an A rating at 1800 rpm - you have full power from 1500 to 1800 rpm.

Extended Oil Change Intervals

A Ratings: 1000 hours, B Ratings: 750 hours, C Ratings: 500 hours
