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/III and EPA Tier 3; the exhaust aftertreatment system, using Selective Catalytic Reduction (SCR) technology, meets EPA Tier 4 and IMO III.
Covered by a comprehensive one year warranty and backed by Cummins global service network
Features may include:
Engine DesignRobust engine block designed for continuous duty operation and long life. Metric o-ring seals and edge molded gaskets eliminate fluid leaks. Ductile single-piece iron piston design with hardened liners and nitride coated rings for exceptional durability. No matter the vessel, Cummins will keep you always on.
Fuel SystemModular Common Rail Fuel System, including New Tier 4 Fuel Pump with Rock Catcher, provides constant high injection pressure regardless of engine speed or load condition. Benefits include low noise and vibration for quiet operation, idle stability and improved low-end torque.
Cooling SystemLow temperature aftercooling. Engine-mounted titanium plate heat exchanger provides superior durability with minimal maintenance requirements.
Exhaust SystemDry exhaust manifold with water shielding for reduced fuel consumption and improved performance.
Air SystemCummins turbochargers optimized for marine applications. Two pump, two loop, low temperature aftercooling for efficient operation and optimization of performance.
Lubrication SystemStandard capacity (261 L [69 gal]) or high capacity (378 L [100 gal]) marine grade oil pan. Pre-lube starter protects engine from damage due to dry starts.
Electronics24v Quantum System electronics feature a proven 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.
CertificationsComplies with EPA Tier 4 / IMO Tier III emissions regulations. Designed to meet the International Association of Classification Societies (IACS) and SOLAS requirements.
Aftertreatment SystemLife to overhaul aligned with engine LTO, lower DEF consumption, (operates with 32.5% or 40% DEF), higher sulfur tolerance, and keeping idle up to speed.
