Caterpillar Releases 2433 HP Marine Engine

By: Scott Way

Following the success of the C32B 2025 mhp engine, Caterpillar Marine has released a larger 2433 mhp (2400 bhp) high-performance iteration. According to the company statement, the new engine will offer a significant 20% increase in power output at a rated speed of 2300 rpm compared to its predecessor. It will incorporate many of the same components as the 2025 mhp, but will also offer additional features and benefits aside from increased horsepower.


The new 2433 mhp version will carry an upgraded cooling system with a sequential 3-turbo air system designed to deliver faster response with all-around stronger performance. Additional options include longer oil change intervals, full MCS certification, duplex filtration, and a cosmetic engine cover. Other notable benefits will include higher overall vessel speed for sport fishers, a more environmentally friendly option for motor yachts, and 2025 mhp Intermittent Duty Classification for governmental applications. The C32B is also designed with repowers in mind to offer streamlined replacement to increase power output to existing vessels. The engine also complies with EPA Tier 3 Recreational and IMO II emissions regulations, serves as a fully integrated SCR solution for IMO III, and comes with industry-leading warranty coverage.


From Allen Bowman, Caterpillar Marine Product Strategy Lead for the C32, “We are extremely excited to build on our recent introduction of the C32B by bringing even more power density to the industry with our best-in-class V12 engine. The C32B Triple Turbo engine will be a difference-maker for the high-performance marine segment, both in power and performance. We’re thrilled to work with our customers, dealers, and builders to deliver this outstanding product.”
