John Deere Engine 10 - 6090AFM85 - Marine Generator Drive Engine
This 9.0L PowerTech™ engine offers high power density at 195-222 kW (261-297 hp) output. It is ideal for patrol craft, launches, work boats, fishing boats, trawler yachts, and sportfishing boats.
Key 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.

6090HFM85 9.0L PowerTech™ engine has 238 kW (325 hp) power rating operating @ 1800 rpm. It is configured to deliver best performance for patrol craft, launches, work boats, fishing boats, trawler yachts, and sportfishing boats.
Key Features
ABS type approved for use on classed & inspected vessel
- Water-cooled exhaust manifold and turbo to meet surface temperature requirements
- Marine Classification Society approved fuel hoses, lube, and oil hoses
4-valve cylinder head
- The 4-valve cylinder head provides excellent airflow resulting in greater low-speed torque and better transient response.
- Cross flow design
Electronic unit injector (EUI) and engine control unit (ECU)
- The EUI fuel system provides variable common-rail pressure, multiple injections, and higher injection pressures, up to 2000 bar (29,000 psi). It also controls fuel injection timing and provides precise control for start, duration, and end of injection.
Air-to-air aftercooled
This is the most efficient method of cooling intake air to help reduce engine emissions while maintaining low-speed torque, transient response time, and peak torque. It enables an engine to meet emissions regulations with better fuel economy and the lowest installed costs.
John Deere electronic engine controls
- Electronic engine controls monitor critical engine functions, providing warning and/or shutdown to prevent costly engine repairs and eliminate the need for add-on governing components all lowering total installed costs. Snapshot diagnostic data that can be retrieved using commonly available diagnostic service tools.
- Controls utilize common wiring interface connector for vehicles or available OEM instrumentation packages; new solid conduit and “T” connectors to reduce wiring stress and provide greater durability and improved appearance.
- Factory-installed, engine mounted ECU and wiring harness and associated components. Industry- standard SAE J1939 interface communicates with other vehicle systems, eliminating redundant sensors and reducing vehicle installed cost.
Additional features
- Gear-driven auxiliary drives
- Self-adjusting poly-vee fan drive
- Single-piece low friction piston
- Low-pressure fuel system with “auto-prime” feature
