THE RUNDOWN

Optimized Engine Design
Updated core components, aftercooler design and electronic controls increase power density and improve durability compared to previous C280 models, supporting productive operation and
lower lifecycle demands
Extreme Duty Construction
Rigorous thermal, overspeed, cold-start and emissions testing, more than 350,000 field hours, heavy-duty construction and marine-hardened electronics support reliable operation in demanding environments.
High Power Density
Flexible Continuous Service and Maximum Continuous ratings deliver 1,730–2,030 bkW at 900–1,000 rpm, with optimized torque at low speeds for varied commercial propulsion requirements.
Extended Service Intervals
Service intervals extend up to 1,400 hours on select configurations. Clear maintenance plans and Cat dealer support help reduce planned downtime and simplify lifecycle service.
ADEM IV Controls
Dual A4 electronic control modules with a rigid wiring harness provide engine control and monitoring
Cooling Flexibility
Heat exchanger or keel-cooled configurations, clockwise or counterclockwise rotation, and right- or left-hand service and water connection options help match vessel installation needs.
