Features

Features

Expand All Collapse All

Water-cooled exhaust manifold

  • Integrated components eliminate external hoses and fittings. Wet exhaust manifold creates a cooler and quieter environment for passengers and crew.

Directed top-liner cooling

  • Reduces upper liner temperature by as much as 100 degrees Fahrenheit (54 degrees Celsius)
  • Durable and reliable power cylinder components

Replaceable cylinder liners

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

Either-side service

  • Oil and fuel filter combinations
  • Application and service flexibility to provide installation convenience plus fast and easy maintenance

Cooling system

  • High-capacity heat exchanger designed for reliable operation in adverse conditions
  • Available as keel-cooled

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.

Fuel system

  • Watercooled turbocharger and exhaust manifold
  • Directed top-liner cooling
  • Replaceable wet-type cylinder liners
  • Either-side service
