Meet The New 2025 mhp Cat® C32B Marine Engine
This Sport Fishing Engine Is the Right Choice for Repowers
More power and more speed, delivered in the same size package and based on a proven design — that’s what you get with the new Cat® C32B. All new from the block up, built on the reliable C32 platform and tested for more than 30,000 hours, this American-made 2025 mhp marine engine isn’t just perfect for new sport fishing boats. It’s the ideal repower solution, whether you’re running an existing C32 at 1825 mhp or 1925 mhp or another engine brand entirely. Here’s why:
1. Run longer at higher horsepower
If you want to get to and from your favorite fishing spot faster, repowering with the Cat C32B is a smart move. With an “E” tier rating, it gives you the power to run at wide-open throttle — the full 2025 mhp — as much as 8% of the time. That’s at least 3% longer than the closest competitor.
2. Drop it in and go
Upgrading from an 1825 mhp or 1925 mhp C32 to the 2025 mhp C32B is simple. The new model is a drop-in replacement, fitting into the same space in your engine room. And don’t worry about added weight slowing you down. The new C32B delivers a 5% power increase over the previous model with just a 2% weight increase. It’s more muscle without more bulk, making it a great choice for repowers.

3. Enjoy the quiet
A day fishing shouldn’t feel like a night at a rock concert. With the new C32B, you can hold a conversation on deck at normal volume even when you’re running at full throttle. Our new 2025 mhp engine is 25% quieter under low-speed conditions thanks to its advanced unit injection fuel system. Similar to common rail fuel systems, this system fires multiple injections of fuel per power stroke to reduce noise. This tried-and-true technology is incredibly reliable and easy to service, too.
4. Restart your warranty coverage
If your older engine is out or running out of warranty coverage, a C32B repower gives you the peace of mind you deserve for up to 10 more years. Like all Cat marine engines, our new 2025 mhp model comes with industry’s best coverage: unlimited-hour protection for the first two years, with the option to add Platinum Extended Service Coverage (ESC) for the next three. When the first five years are up, have your Cat dealer inspect the engine and add another five years of ESC.
5. Add other upgrades
The time your boat’s off the water for a C32B repower is the perfect time to make other updates. Consider upgrading to the newest Cat color displays as well as to Cat controls — your dealer can order the engine and controls together and send the package to the shipyard to make the process faster and more convenient. You also can bundle extended protection for your engine and controls with Platinum Plus ESC.
6. Spend more time fishing
After your C32B repower, make sure you keep using the proper Cat filters (white to match your engine) and fluids and work with your dealer to take regular S•O•SSM fluid samples. Why? Doing so likely will let you extend your oil change interval out to 500 hours. That means less time spent on maintenance and more time spent on the water.
Now’s the time to schedule your C32B repower, so get ahold of your Cat dealer today to place your order for this new 2025 mhp marine engine. Make sure to ask what else is coming soon to our sport fishing engine lineup — you won’t want to miss it.
