Features
Optional low rpm operation
- 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.
4-valve cylinder head
- Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.
High-pressure common-rail (HPCR)
- The HPCR fuel system provides variable common-rail pressure, multiple injections, and controls fuel injection timing and provides precise control for the start, duration, and end of injection.
Water-cooled exhaust manifold
- Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.
Replaceable cylinder liners
- Replaceable wet-type cylinder liners are precision-machined and hardened for long life. Allows engine to be rebuilt to original specifications.
Electronic engine control unit (ECU)
- Advanced fault code diagnostics and customizable engine protections ensure reliability and uptime. Provides highly customizable features and trim to integrate your vessel.
Keel-cooled or heat exchanger
- 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.
Multiple service options
- Either-side oil fill/dipstick combinations and remote oil and fuel filter options are available for easier service access.
