 Features and Benefits

Watercooled Turbocharger and Exhaust Manifold

  • Cooler and quieter environment for vessel and crew
  • Reduced external connections eliminates hoses and fittings that can leak or break

Directed Top-liner Cooling

  • Reduces upper liner temperature by as much as 130 degrees Fahrenheit (72 degrees Celsius)
  • Durable and reliable power cylinder components

Replaceable Wet-type Cylinder Liners

  • Hardened and precision machined for long life

Corrosion Resistant Components

  • Provides engine protection from the effects of seawater

Gear Auxiliary Drive

  • Optional auxiliary drive for wash-down pumps, hydraulic oil pumps, and air compressors

Either-side Service

  • Oil fill and dipstick combinations
  • Application and service flexibility to provide installation convenience plus fast and easy maintenance

Heat Exchanger or Keel Cooled

  • High-capacity heat exchanger designed for reliable operation in adverse conditions
  • Keel cooler options provide application flexibility

High Torque and Low Rated RPM

  • Enables the engine to turn larger propellers at lower speed for best efficiency
  • Excellent vessel control and maneuvering
  • Lower rated rpm limits vibration and noise for better crew comfort

Fuel System

  • Electronically controlled unit injectors provide precise fuel delivery with variable timing resulting in excellent fuel economy and excellent performance
  • 3-5% Generator Droop Governing
  • Self diagnostics and protection
  • Electronic instrument panel with plain text messaging
