Features + Benefits

Four cycle, 4 cylinder, liquid cooled overhead valve diesel. The induction hardened, forged carbon steel crankshaft is stronger than cast iron while the cross flow head makes for more efficient breathing. Helical cut and ground, carbon steel timing and PTO gears reduce noise.

Standard keel cooling. Cast aluminum expansion tank with coolant recovery type filler cap. Thermostat for quick warm up and safety. Cast iron exhast manifold has two pass jacket-water flow for even temperature.

Easy to service mechanical, indirect injection fuel system. Spin on fuel filters with air bleed. Mechanical fuel transfer pump with manual priming plunger.

The M30C3F is fully compliant with the US EPA Tier III emission standards. Its dry air filter silences intake noise.

Full-flow, spin-on filter with bypass. 10.5 qt (10 ltr) center well oil pan. Closed crankshaft vent system keeps oil vapor inside engine room.

The DC system uses reliable relays instead of unrepairable circuit boards. 12 volt system includes circuit breaker, starter motor and alternator.

Standard flush mount S-3C control panel has hour meter, oil pressure gauge, coolant temperature gauge, DC voltmeter, stop-start switch and preheat switch. Expandable up to six panels, up to 110 feet from the set. Low oil pressure and high coolant temperature shutdowns are standard.

The Northern Lights, direct coupled, four pole generator has Class “H” insulation, a pre-lubricated bearing and features a conservative heat rise rating of 95°C/50°C ambient. Engines and generators are torsionally matched for long life. Automatic Voltage Regulator (AVR) gives quick +/-1% RMS no load to full load voltage regulation.

Northern Lights Commercial Series gensets are made for the demands of the marine environment, with features including a rugged, welded steel base frame, captive vibration isolation mounts and a belt guard for operator protection.

Match your generator set to your job requirements. Optional equipment includes front power take-off (PTO) with 12 or 24v electric clutch and SAE B spline providing up to 42 HP. Heat exchanger cooling is available with 3 inch wet exhaust. Add a dry muffler with 18” SS flex. Alarms or shutdowns can be installed for low oil level, raw water flow, overspeed, and others.
