Cat C32B: Walk Around
Discover with the Cat Service Trainer the main innovations of the new Marine Cat C32B engine.
The US-made C32B Cat is the new generation of the tested and reliable C32 platform, a more powerful version of an already known and appreciated product. The new C32B Cat, available in 2025 and 2433 mhp versions, has been subjected to severe tests to ensure its reliability: over 54,000 hours overall., The 2433mhp Cat C32B is a 12-cylinder shredder, the most powerful available in its class today. The whole C32B range complies with EPA Tier 3, IMO II regulations, which can be integrated with SCR (switchable version) to become IMO III, shorter, lighter and with more torque than a competitor's 16V engine. Available with MCS “Type approval” certifications in all its calibrations.
More horsepower means more speed and the marine Cat C32B from 2025-2200 to 2400mhp versions, will get you wherever you want faster than before. Moreover, with an "E Rating" working curve, the Cat C32B gives you the power to sail the sea at full throttle up to 8% of the time. It is at least 3% higher than the competition. The 2433mhp Cat C32B, 12-shredder cylinder, it is the most powerful marine engine in its class.
Even if it is more powerful, the C32B is much quieter than its predecessor - up to 25% less at a low speed. This is thanks to the advanced injection fuel system, which like the common rail fuel systems used on other high-powered engines, fires more fuel injections while reducing noise.
The upgrading from an 1825mhp or 1925mhp C32 to the 2025mhp C32B is simple. The new model is a drop-in replacement, which fits into the same space in the engine room. And do not worry the extra weight won’t slow you down. The new C32B has 5% more power than the previous model with only 2% heavier weight. It is more muscular with no more mass, a great choice for repower.
As the engines become more powerful, the system’s cleaning becomes more important. C32B's Ultra High Efficiency Plus filters hold more contamination so engine components last longer. Matched with the periodical CGT lubricants’ analysis, they can extend the oil change interval to 500 hours.
The new Cat C32B is warranted for the first two years * regardless of hours. And not only, it is possible to add Extended Service Coverage (ESC) for another three years. By carrying out all the maintenance planned with CGT during the first five years, after an engine inspection you can add another 5 years warranty. That is a total of 10 years of coverage and confidence every time you get out on the water. * 24 months of coverage are for private use, they become 12 months in other cases (e.g. rental yacht)
