    Features

    • High torque provides excellent vessel control and maneuverability. Lower rated propulsion RPM reduces vibration and noise for improved crew comfort.

    • Cooler turbocharger operation enables higher ratings and efficiencies or applications that require high power or speed.

    • Standard front fuel service, optional left-hand or right-hand oil filter options for twinengine applications.

    • Integrated components eliminate external hoses and fitting

    • 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.

    • Advanced fault code diagnostics and customizable engine protections ensure reliability and uptime. Provides highly customizable features and trim to integrate your vessel.

    • Replaceable wet-type cylinder liners are precision-machined and hardened for long life. Allows engine to be rebuilt to original specifications.

    • Excellent airflow through 4-valve cylinder head delivers greater low-speed torque and better transient response time.

    • Integrated expansion tank, heat exchanger, and exhaust manifold reduce the chance of leaks. High-capacity heat exchanger provides reliable operation in adverse conditions.

    • Internal balancers reduce engine noise and vibration for crew comfort.
