Information
2018 John Deere Engine & Drivetrains 6090AFM85 (285-425 hp) M4
Marine Propulsion Engine
Features may include:
High torque and low rated RPM
High torque provides excellent vessel control and maneuverability. Lower rated propulsion RPM reduces vibration and noise for improved crew comfort.
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.
