38/32 kW: M944T

Engine Block

  • Four cycle, 4 cylinder, dry turbocharged, overhead valve diesel.
  • Induction hardened crankshaft. Forged carbon steel – stronger than cast iron.
  • Helical cut and ground, carbon steel timing and PTO gears reduce noise.
  • Cross flow head for efficient breathing.

Cooling System

  • Freshwater cooling system in heat exchanger or keel cooled configuration.
  • Large single-piece exhaust manifold is freshwater cooled for safety. No hot, dry risers. Fewer troublesome hoses and gaskets. Cast iron to resist corrosion and electrolysis.
  • Zinc anode electrolysis protection.
  • Heat exchanger cooling is standard. Cupro-nickel tube-type heat exchanger has removable ends for easy cleaning. Rubber impeller seawater pump of bronze and stainless steel is gear driven; no belt.

Fuel System

  • Direct injection with glow plugs.
  • Bosch-type in-line injection pump with 5% mechanical governor for close AC frequency control.
  • Pintle injectors.
  • Mechanical lift pump with hand primer. No electric pump to fail.
  • Large spin-on fuel filter.
  • Flexible fuel lines routed to base.
  • Stop solenoid controls the fuel rack, not the throttle, to eliminate speed variances and linkage problems.

Intake and Exhaust

  • Meets US EPA Tier III emission standards at date of manufacture.
  • Dry turbocharger insulated for safety.
  • Washable air cleaner in cast intake manifold reduces intake noise.
  • Wet exhaust elbow for safety.

Lubrication System

  • Full flow, spin-on oil filter with bypass.
  • 10.5 qt (10.0 ltr) center well oil pan. 250 hour oil change intervals.
  • Oil drain for quick, clean oil changes.

DC Electrical System

  • DC system uses reliable relays instead of an unrepairable printed circuit board.
  • 12 volt starter motor and battery charging alternator with regulator and belt guard.
  • Standard panel: Remote mount S-3C has hour meter, stop-start switch with run light and preheat switch. Gauges for oil pressure, coolant temp and DC voltage. Safety shutdowns for low oil pressure, high coolant temp and high exhaust temp.
  • Expandable to six panels up to 110 feet from the set.
  • 20 foot (6m) plug-in panel harness lets you mount your panel anywhere onboard.

AC Generator

  • Northern Lights, direct coupled, brushless AC generator is maintence free. 12 wire 60 Hz output standard. Conservative heat rise rating: 95oCS/50oC ambient.
  • Automatic voltage regulator (AVR) is powered by dedicated AC winding for true 300% short circuit capability and circuit breaker protection. Quick ±1% RMS no load to full load voltage regulation.
  • Generator features high quality, Class “H” epoxy insulation, accessible diodes, over-sized bearings and junction box for wiring.

Special Equipment

  • Welded steel base frame with drip pan.
  • Four plateform mounts isolate vibration.
  • Belt guard protects operator.
  • White, long-life polyurethane paint.
  • Operator’s and parts manuals standard.

Classification Standards

  • Consult factory for details.
