Sequential Turbocharging

Optimized sequential turbocharging delivers strong low-end torque and rapid throttle response, helping support quick acceleration, confident maneuvering and high-speed runs for sportfishing and performance yachting applications.

High Power Range

Delivers 1800–2400 bhp up to 2300 rpm, providing the horsepower needed for fast offshore runs, responsive operation and demanding high-performance marine applications.

Compact Power Density

High power density with minimal weight increase helps support new builds and repowers, giving owners strong performance without requiring a move to a larger engine platform.

Refined Low-Speed Operation

Reduced noise and vibration at low engine speeds help create a more comfortable onboard experience during trolling, cruising and long days on the water.

Flexible Emissions Options

Certified for IMO II / IMO III with SCR, U.S. EPA Tier 3 Recreational, RCD and China II, with airless aftertreatment options that help reduce system complexity and maintenance needs.

Global Cat Support

Backed by the global Cat dealer network, providing access to marine engine expertise, parts and service support wherever the vessel operates.
