Boat diesel generator set (5-10 KW)
M673L3 : 5 - 6 kW (shown with optional sound enclosure) Northern Lights

The Northern Lights M673L3 is everything you want in a generator set, and nothing you don't. At 6.0 kW (5.0 kW for 50 Hz applications), it's the right size -- big enough to run many shipboard items and start sizeable motors, yet small enough to fit into tight engine rooms.

The M673L3 runs at 1800 rpm (60 Hz), not 3600 like sets built to a slightly smaller envelope or to a slightly smaller price. That slower speed means quiet, smooth operation and much less stress on the engine. During 2000 hours of operation, the M673L2 will turn over 216 million fewer revolutions; its pistons will travel 43,337 fewer miles; and its cylinders will withstand 108 million fewer detonations. Now, which engine do you think will last longer? So do we.
