M844LW3 Northern Lights Marine Generator

Northern Lights Marine Generators

20 kW @ 60 Hz / 1800 rpm | 16 kW @ 50 Hz 1500 rpm

These are the powerhouses that go in vessels that need continuous AC power to operate. Unfortunately, some 20 kW machines have small displacement, light duty diesels that can’t stand up to heavy use. Some even need turbochargers to compensate for their small displacement.

The M844LW3 is different. Powered by a naturally aspirated, four cylinder, 2.2 liter (135 cid) Lugger diesel, this set has the low end torque needed to start bigger electric motors without breaking a sweat.

The M844LW3 meets US EPA Tier III emission standards to protect the environment you enjoy.

Vibration isolation mounts, air intake silencer and cast manifolds make the set remarkably smooth and quiet. A high attenuation sound enclosure is optional.

Northern Lights generator sets are simple to operate and maintain. A 20 foot wire harness and control panel lets you operate it from your boat’s bridge. The engine’s DC electrical system uses reliable relays instead of delicate printed circuit boards. If a failure should occur, you can simply plug in an inexpensive relay. All service points are on one side within easy reach. The sea water pump is up front for easy impeller changes.

Need hydraulic power? Add an optional electric clutch front PTO.
