M773LW3 Northern Lights Marine Generator

Northern Lights Marine Generators

9 KW @ 60 HZ / 1800 RPM | 7KW @ 50 HZ 1500 RPM

The M773LW3 incorporates the best Northern Lights features into one compact and versatile package. It meets growing onboard power demands without asking for a lot of engine room space.

The M773LW3 was engineered to deliver its power at a quiet, long lasting 1800 rpm. Driven by a high-torque, 69 cubic inch, Lugger diesel and fitted with a powerful W-Series generator end, the M773LW3 has the power to start electric motors with ease.

Like all Northern Lights, simplicity and longevity are the focal points. Hoses and belts have been eliminated wherever possible. The closed crankcase vent system traps oil vapor emissions keeping the engine room, and environment, cleaner.

The M773LW3 features single-side service, which means it can be mounted with the non-service side facing a bulkhead without compromising routine service access.

Other proven systems are utilized throughout. The DC system has simple relays, instead of a printed circuit board, for quick, inexpensive field repairs. Low oil pressure, high coolant temperature and high exhaust temperature safety shutdowns are standard.

An automatic voltage regulator keeps voltage to within ±1%. Vibration isolating plateform mounts, gleaming white polyurethane paint and a plug-in wire harness complete the package.

Northern Lights accessories can make this extraordinary genset into the perfect power source for your vessel. Choose from the long list of optional equipment that includes control panels, super attenuated sound enclosures and much more.

The M773LW3 meets the US EPA Tier III and IMO emission requirements.
