ENGINE PLATFORMS PROVEN TO PERFORM ACROSS MARINE INDUSTRIES

of

From harbor tugs to cruise ships, articulated tug barges to ferries and even whale-watching vessels, you’ll find Cat® Tier 4 Final engines powering vessels across marine industries. Our entire lineup — main engines and auxiliary generator sets — meets Tier 4 Final and IMO III marine emissions regulations. By using Selective Catalytic Reduction to reduce emissions downstream of the engine, we didn’t need to redesign our products. You get the same iron you’ve always counted on to perform in tough marine environments.
