Cummins offers a complete line of variable speed propulsion solutions designed specifically for the challenges of commercial, government and recreational marine applications.

Our propulsion line includes the mechanical K and N Series and the electronic Quantum Series.

Both the N Series and the K Series have proven reliable and durable in tough marine environments for over 25 years. Many of our NTA855 and KTA19/38/50 propulsion ratings are now certified to meet more stringent IMO Tier II global emissions standards.

The Quantum Series product line was introduced in 2005 to meet the U.S. Environmental Protection Agency’s stringent Tier 2 emission standard. Today the product line is certified to current EPA, IMO and EU regulations and will serve as the platform for future more stringent standards.
