C32 IMO II
Cat C32 Propulsion Engine (IMO II)
The C32 marine propulsion engine is available at ratings that meet IMO II emissions regulations. It has a separate circuit aftercooling system (SCAC) for A through C ratings, six 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 Caterpillar’s standard warranty.
Emissions
IMO II - meets the International Maritime Organization's Regulation 13 of Revised Annex VI to the MARPOL Convention.
Worldwide Support
Extensive service network of Cat Dealers and unparalleled service from authorized marine dealers
Durability
The C32 ACERT has proven engine operating history. It consists of performance iron with thousands of hours of validation testing for quality and durability.
Reliability
Backed by Caterpillar's standard warranty
Six Ratings with Wide Operating Speed Range (WOSR)
Excellent reserve power for acceleration, Ideal for applications requiring the engine to operate normally at more than one speed or load, Provides an alternative to torque converters, multi-speed transmissions, Controllable Pitch Propeller (CPP)
Extended Oil Change Intervals
Seperate Circuit Aftercooling System: A-C Ratings
No seawater circulating through the aftercooler, isolator mounts available as optional attachments, mounting and isolator base require wider stringer without vertical adjustment nut (adjustable height), thrust (recommended for remote gear) and non-thrust (recommended for close gear) options available
