  • Designed to withstand the challenging conditions commercial marine operators often face; this same reliable, durable power is now available for recreational boating applications, including super yachts and yacht support vessels.

  • Improved idle stability and reduced noise and vibration are a direct result of the Cummins Modular Common Rail fuel system.

  • In-cylinder technology to meet IMO Tier II, EPA Tier 3 and EU Stg. 3a; platform for future emissions globally.

  • Covered by a comprehensive one year warranty and backed by Cummins global service network.

  • Built at Seymour Engine Plant in Seymour, IN, U.S.


  1. Engine Design : Reliable base engine uses common components from the proven K19, K38 and K50 engines. A new cast-iron, ductile single-piece piston with nitride-coated rings and hardened cylinder liner provides excellent durability and long life.

  2. Fuel System : Modular Common Rail Fuel System features a simplified design which provides constant high injection pressure regardless of engine speed or load condition. Benefits include low noise and vibration for quiet operation, idle stability and low-end torque.

  3. Cooling System : Single-loop cooling eliminates the need for two keel coolers for reduced installation expense. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements.

  4. Exhaust System : Water-cooled exhaust manifold cools engine surface temperatures. Design is a cast single piece construction that eliminates potential exhaust leakage.

  5. Air System : Mounted or remote marine grade air cleaner with replaceable element reduces maintenance cost. Water-cooled turbocharger optimized for vessel operating conditions and safety.

  6. Lubrication System : Standard capacity 60.6 L (16 U.S. gal) shallow oil pan or high capacity 72 L (19 U.S. gal) deep oil pan for installation flexibility. Cummins spin-on oil filters available on engine service side.

  7. Electronics : 24v Quantum System electronics feature a proven CM850 ECM to monitor operating parameters, while providing diagnostics, prognostics and complete engine protection. Simplified electrical customer interface box for all vessel connections reduces installation complexity.

  8. Certifications : Complies with IMO Tier II, EPA Tier 3 and EU Stage IIIa emissions regulations. Designed to meet International Association of Classification Societies (IACS) and SOLAS requirements. Consult your local Cummins professional for a complete listing of available class approvals.
