  • A lower speed option provides the user the ability to start the engine without going to the gen-set rated speed and allows the user to clutch in an accessory that may be driven by the engine.

  • Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.

  • The HPCR fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures. It also controls fuel injection timing and provides precise control for the start, duration, and end of injection. Electronic transfer pump is self-priming for ease of maintenance. Provides high performance, excellent fuel economy, and low emissions.

  • Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.

  • Replaceable wet-type cylinder liners are precision-machined and hardened for long life. Allows engine to be rebuilt to original specifications.

  • Advanced fault code diagnostics and customizable engine protections ensure reliability and uptime. Provides highly customizable features and trim to integrate your vessel.

  • Integrated expansion tank, heat exchanger, and exhaust manifold. High-capacity heat exchanger provides reliable operation in adverse conditions.

  • Closed cooling system in keel-cooled engine option eliminates the need for a sea strainer, seawater pump, or anodes. Heat exchanger option offers a lighter, more compact, and simpler engine installation.

  • Internal balancers reduce engine noise and vibration for crew comfort. NOTE: John Deere 4045 engines only.

  • Either-side oil fill/dipstick combinations and remote oil and fuel filter options are available for easier service access.
