Built on John Deere’s proven 9.0L PowerTech™ platform, this generator drive engine delivers up to 373 horsepower while maintaining the efficiency, durability, and performance required for continuous-duty operation.
Advanced electronic engine controls, a high-pressure common rail fuel system, and air-to-seawater aftercooling help optimize performance and fuel efficiency while supporting long service life. With features such as a water-cooled exhaust manifold, replaceable wet cylinder liners, and flexible service options, the 6090SFM85 is built to maximize uptime and provide dependable power for commercial fishing vessels, passenger vessels, workboats, and government fleets.
Features & 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.
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.
Turbocharged with air-to-seawater aftercooling
Cooler turbocharger operation enables higher ratings and efficiencies for applications that require high power or speed.
Replaceable cylinder liners
Replaceable wet-type cylinder liners are precision-machined and hardened for long life. Allows engine to be rebuilt to original specifications.
