  • Building on the KTA38’s reputation hard earned on the U.S. inland rivers.

  • 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 in the U.S. and globally.

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

  • Built at Daventry Engine Plant in Daventry, U.K.


  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 : Two-pump, two-loop, low temperature aftercooling maximizes efficiency and improves performance. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements.

  4. Exhaust System : Dry-shielded exhaust manifold and turbocharger. Vertical or horizontal exhaust connections available for installation flexibility.

  5. Air System : Turbocharger optimized for vessel operating conditions and safety. Mounted or remote marine grade air cleaner with replaceable canister reduces maintenance cost.

  6. Lubrication System : Standard capacity 151 L (40 gal) and high capacity 204 L (54 gal) marine grade oil pan. Handed Cummins spin-on oil filters available for easy accessibility and servicing.

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

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