Features and benefits
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.
High-pressure Common-rail (HPCR)
- 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.
Water-cooled Exhaust Manifold
- Integrated components eliminate external hoses and fittings
that can leak or
break. 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
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.
Internal Balancers
- Internal balancers reduce engine noise and vibration for crew comfort.
John Deere 4045 engines only.
Multiple Service Options
- Either-side oil fill/dipstick combinations and remote oil and fuel filter options
are available for easier service access.
for long life. Allows engine to be rebuilt to original specifications.
