Features + Benefits

  • Six cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavyduty industrial engine blocks.
  • Balanced, forged crankshaft with induction hardened journals and rolled fillets for long life.
  • Replaceable, wet cylinder liners for long life and low rebuild costs.
  • Bimetallic valves with chrome stems and rotators.
  • Replaceable valve seats and guides.
  • Three ring aluminum alloy pistons with Ni-Resist insert for the top ring. Keystone piston ring reduces carbon buildup under light loads.
  • Torsional crankshaft dampers help ensure smooth operation.
  • A single poly-vee drive
  • High pressure common rail fuel injection for smooth, clean delivery.

  • Electric fuel pump integrated into primary fuel filter. Computer controlled priming for ease of operation.
  • Positive displacement gear-type oil pump.
  • Full flow, spin-on oil filter.
  • Jacket-water, plate-type, full flow oil cooler reduces heat and prevents lube oil breakdown.
  • Large capacity oil pan.
  • A closed loop crankcase vent traps oil vapor to keep the engine room clean.
  • Dry air filter silences intake noise.
  • Turbocharger with jacket water cooled turbine housings for safety.
  • Jacket water aftercooler provides optimized combustion and output. No second keel cooler needed.
  • Keel cooled with heat exchanger option
  • Gear driven, belt-less sea water pump with flexible impeller made of bronze and stainless steel.
  • Cast iron expansion tank with brass filler neck.
  • Two thermostats for quick warm-ups and safety.
  • Cast-iron exhaust manifold for reliable temperature control.
  • Negative ground, 12 volt DC system has on-board controls, starter motor and alternator with regulator.
  • Optional S-3C remote control panel with engine hour meter, coolant temperature gauge, oil pressure gauge, DC voltage meter, start-stop and shutdown bypass switches. Additional optional panels help you specify the amount and type of information delivered.
  • Low oil pressure and high coolant temperature safety shutdown system.
  • Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design.
  • All NL generators meet or exceed class society standards with Class “H” insulation, accessible diodes, oversized ball bearings, marine grade shafts and conservative 90°/50° heat rise ratings.
  • Engines and generators are torsionally matched for long life.
  • Automatic voltage regulator; ±1.5% regulation over the entire range from no load to full load.
