Commercial Propulsion Engines

Industry-leading technology allows Caterpillar to create the most reliable commercial engines for a variety of applications. From tugs and container vessels to yachts and sport fishers, Cat and MaK engines have demonstrated their efficiency countless times. With remarkable reliability and durability, these engines will exceed your expectations for decades.

3516C Marine Propulsion Engine (Tier 4)

The 3516C propulsion engine has available ratings of 2240 and 2350 bkW that are U.S. EPA Tier 4 emissions certified, IMO II certified, and IMO III compliant. Installation of these engines utilizes the latest advancements in Caterpillar designed Selective Catalyst Reduction (SCR) technology to comply with EPA and IMO emissions levels while minimizing customer integration impact and maximizing operating efficiencies. The 3516C engine’s design greatly enhances the back pressure capability, allowing the Cat Clean Emissions Module to be the most compact and efficient SCR system. Specifically designed for Marine applications, the Cat Clean Emissions Module offers versatile vessel integration options, serviceability, and lowest cost of ownership.
