Description

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. 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. Heat exchanger High-capacity heat exchanger provides reliable operation in adverse conditions. Multiple service options Either-side oil fill/dipstick combinations and remote oil and fuel filter options are available for easier service access.
