373-597 kW | 500-800 hp
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.
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
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
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
Exhaust System – Water-cooled exhaust manifold cools engine surface temperatures. Design is a cast single piece construction that eliminates potential exhaust leakage
Air System – Mounted or remote marine grade air cleaner with replaceable element reduces maintenance cost.
