Model Photo

6090SFM85

  • 9.0L PowerTech™
  • 222-278 kW (297-373 hp)

 

Features

Optional low rpm operation

  • A lower speed option provides the user the ability to start the engine without going to the gen-set rated speed and allows the user to clutch in an accessory that may be driven by the engine.

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.

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.
