Caterpillar Marine has launched a new marine engine with a rated engine speed of 2300 rpm.

The Cat C32B high performance 2000 HP (2025 MHP) meets emerging market demands and expands the power capability of the C32 high performance product line, delivering a reported 5% power increase over existing C32 ratings.

“We’re very excited to offer our customers more power with the C32B engine, while also helping to reduce engine noise and continuing to provide excellent engine performance and reliability,” said Allen Bowman, marine product strategy engineer for Caterpillar Marine.

“The C32B will provide expanded opportunities for our customers for new builds and repower options, which is generating excitement about the future of the C32B and what it will bring to the market,” he added.

The engine will be available with the same emissions certifications as the current C32 high performance ratings including EPA Tier 3 Recreational and IMO II. Beyond power density improvement, additional benefits include updated electronics (ADEM 6 ECM) and an enhanced unit injector fuel system enabling multiple injections to help improve noise and vibration characteristics from combustion.
