John Deere engines give you an effective blend of pure power and rugged durability. From 60 to 559 kW (80 to 750 hp), our complete, high-horsepower lineup offers the right engines for your needs. John Deere engines build power faster for cruising at higher speeds with lower rpm. Boost your vessel’s performance in wind, swells, tides, or currents with reliable power that’s ready when you are. 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 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. 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.
