6090AFM85

Marine Propulsion Engine
  • 9.0L PowerTech™ 
  • 213-317 kW (285-425 hp)

Features

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.

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.

Keel-cooled or heat exchanger
  • Closed cooling system in keel-cooled engine option eliminates the need for a sea strainer, seawater pump, or anodes. Heat exchanger option offers a lighter, more compact, and simpler engine installation.

Multiple service options
  • Either-side oil fill/dipstick combinations and remote oil and fuel filter options are available for easier service access.
