Cummins QSK38 is built upon the KTA38’s hard-earned reputation on the U.S. inland river waterways. Available at 800hp for propulsion and auxiliary applications, this U.S. EPA Tier 3 compliant engine delivers innovation and dependability without the use of aftertreatment. Designed to withstand even the most challenging conditions commercial marine operators face, the QSK38 is covered by a comprehensive on year warranty and backed by a fully-owned distribution network around the world.

While operating at 800hp, the QSK38 is below the power threshold (600kW/805hp) for EPA Tier 4 requirements, and therefore can operate at EPA Tier 3 emissions levels without the use of aftertreatment. Additionally, this solution is superior to others on the market as the life-to-overhaul period is twice as long in certain instances.

Cummins QSK19 is available between 500hp – 800hp for propulsion and auxiliary applications. Designed to withstand even the most challenging conditions commercial marine operators face, this engine experiences improved idle stability and reduced noise and vibration as a result of Cummins’ modular common rail fuel system. The QSK19 is covered by Cummins comprehensive one-year warranty and backed by our fully-owned service network around the world.
