M944W3 Generator

Big power in a little package, the Northern Lights M944W3 is ideal for the boater who expects unparalleled excellence from his generator set without sacrificing valuable engine room space.

Cranking out 30 kW at 60 Hz (1800 rpm), the M944W3 is intended for long life at full load. At more than 3.33 liters, this four cylinder dynamo has the displacement (203 cid) to shoulder the large loads. The generator is driven by a reliable Lugger engine, drawing its strength from an industrial block designed for 2500 max rpm; not the 3600 rpm automotive engine that is most common in the industry. This is the reason that our M944W3 hits the top of its torque curve at 1800 rpm instead of sliding down the back of it.

The block is impressive, but what makes the M944W3 so well adapted for the rigors of at-sea use is Northern Lights’ exclusive marinization package. From the cupro-nickel heat exchanger to the bronze/stainless gear driven seawater pump, no detail has been overlooked in engineering a superior marine product. The freshwater cooled exhaust manifold is sturdy cast iron with no dry risers.

The M944W3 features Northern Lights’ revolutionary W-Series generator end for clean AC output and real short-circuit protection. The air filter is cast aluminum for a more quiet operation. The M944W3 meets all of the US EPA Tier III emission requirements.

Producing AC is hardly the M944W3’s only trick. Add a 90 amp DC alternator and you’ll never run out of battery power again. Add a front PTO with an electric clutch for hydraulic power and drive your winches, bow thrusters or deck gear with the simple touch of a button.

Reliable, durable, simple to use, and maintain. For nearly 50 years, this has been the hallmark of all Northern Lights products. The tradition of excellence continues with the M944W3.
