M673L3 Northern Lights Marine Generator

6 kW @ 60 Hz / 1800 rpm | 5 kW @ 50 Hz 1500 rpm


Northern Lights

The ideal 6kW generator set is small and lightweight. The M673L3 certainly qualifies. But it stands apart through its remarkable long-life reliability. The reason? The M673L3 runs at 1800 rpm (1500 rpm for 50 Hz), instead of 3600 rpm.

Consider that during only 2000 hours of operation the 1800 rpm M673L3 will turn 216 million fewer revolutions than a 3600 rpm set. Its pistons will travel 38,522 fewer miles. Its cylinders will withstand 108 million fewer detonations. Which engine do you think will give more years of reliable service? We couldn’t agree more.

The M673L3 has a balanced Lugger three cylinder diesel instead of a rough two banger. Four plateform isolation mounts reduce vibration transmission even more.

For maximum comfort afloat the new M673L3 has a Sound Maze air intake system. Air enters through a molded rubber hose and an acoustic dampening chamber. Air goes in but much less noise gets out. For maximum sound attenuation, specify a sound enclosure. It is constructed of electrogalvanized steel panels with a powder-coated auminum extruded framework, and creates a 23% smaller overall package than previous versions.

The generator’s automatic voltage regulator is powered by an auxiliary AC stator winding that isolates it from the main windings. The AVR always has clean power to provide excitation for faster load response and better motor starting. Your air conditioner and other motor driven equipment will love being matched with the 673.

A 30 amp AC circuit breaker in the junction box protects your wiring. Safety shutdowns for low oil pressure, high coolant temperature and high exhaust temperature protect your engine.

The M673L3 meets US EPA Tier III emission standards. You, your moorage neighbors and the environment will all benefit.

1800 rpm reliability, low emissions, quiet operation and strong motor starting. Good things do come in small packages.
