  • Proven legacy in tough commercial marine environments, hard earned over the last 25 years.
  • 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.
  • IMO Tier I certified and many ratings are also IMO Tier II certified.
  • 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 – Low profile for ease of installation and service. Replaceable wet cylinder liners offer longer life and lower rebuild cost. Gallery cooled pistons for maximum durability.
  2. Fuel System – Dependable Cummins PT fuel system can be operated mechanically or with CENTRY electronics for precise engine fueling. Step Timing Control (STC) allows for smooth engine acceleration under load.
  3. Cooling System – Keel cooled or engine mounted plate heat exchanger for reduced installation cost and less maintenance. Spin-on Cummins water treatment filters for protection against cooling system corrosion.
  4. Exhaust System – Dry exhaust manifold with water shielding for reduced fuel consumption and improved performance.
  5. Air System – Marine grade air filters with air inlet restriction indicator. Twin Cummins turbochargers optimized for marine usage.
  6. Lubrication System – Standard (151 L [40 gal]) or high capacity (185 L [49 gal]) marine grade oil pan. Cummins spin-on oil filter cartridge available for simplified service.
  7. Electronics – 24-volt standard electrical system with 12-volt option available. Marine grade wiring harness.
  8. Certifications – Complies with IMO Tier II emissions regulations .
