You’re well acquainted with the trials that come with sportfishing. The blisters and calluses that tell stories of fighting hundreds of pounds of fish hour after hour. And, you likely know the frustration that comes with an engine that can’t keep up with your passion. To match your unflinching drive and determination, Cat® Marine developed the Cat C32B. The latest, high-power-density marine propulsion solution from a legacy of tried-and-true engines.
Highest Powered V12 in Its Class
The Cat C32B, one of the most powerful 12-cylinder marine engines in the industry, is capable of accelerating from 1,925 mhp to 2,433 mhp at 2,300 rpm, with its sequential turbocharging air system. It can easily power many of the largest sportfishing vessels while meeting IMO II and U.S. EPA Tier 3 (recreational) emissions requirements.
Enhanced Engine Design
Other advancements in engine design, like multi-shot injection technology and improved raw water cooling system, provide a 25% noise reduction compared to previous models. The C32B also readily connects with a vessel’s existing bonding system, eliminating the need for dedicated zinc anodes. Plus, its new closed crankcase ventilation system has up to 2X longer service life, reducing maintenance costs.

Ease of Installation
The C32B is designed to make repowering existing boats or building new straightforward. With similar mounting locations and dimensions, this engine is a true drop-in solution when upgrading from a C32. Its small footprint means less square footage is allocated to the engine room, freeing up space to accommodate those record-breaking catches.
The Right Choice
From its clean, minimalist aesthetic to its power output, the C32B is the highest powered V12 in its class. Whether repowering or building new, the Cat C32B provides reliable performance that brings you to the best fishing spots, fast. And, to ensure the adventure keeps going, Cat® Concierge sets you up with 24/7 support, interval servicing and recommended maintenance anywhere in the world with the Caterpillar global dealer network.
