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.
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.
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.
