Cummins Marine Engines

Reliable, Clean, Quiet - and Powerful.

Cummins has a strong marine heritage dating back to the Company’s start in 1919. More than 90 years later, Cummins continues its legacy of providing reliable, durable diesels to the marine market with a broad range of power 5.9 to 95 liters for commercial, government and recreational applications.

Cummins marine engines have been engineered to meet the durability and performance needs of marine applications and seawater cooling options and controls seamlessly integrated to ensure the propulsion for your vessel meets your needs.

Because we understand that customer needs and operating conditions vary, we also offer custom packaging through our distribution channel. Cummins offers a range of engines packaged with the customer’s choice of engine monitoring and control system and alternator, including our own STAMFORD and AvK brands.

Cummins employs an experienced team of technical and market experts focused on the marine industry and its customers. Factory-trained Marine Application Engineers will help you select the right spec for your application, while Qualified Marine Technicians keep you up and running.

Our team works closely with partner suppliers and customers from vessel concept and continuing through installation, testing and commissioning, to guarantee a product perfectly matched to vessel design, operating conditions and local content requirements.

Cummins marine engines are backed by the largest service network in the industry, including Regional Response Teams for commercial fleets and Cummins Care Marine Experts for recreational boaters – ensuring service and application expertise is available when and where it’s needed.

Whether you’re transporting cargo up and down the Mississippi River, providing supplies to oil rigs in the Gulf of Mexico, fishing for King crab in the Bering Sea, or relaxing with friends in the Caribbean, Cummins has a product for you.
