M773LW3 Generator

The M773LW3 incorporates some of the best Northern Lights features into one compact and versatile package. It meets growing onboard power demands without using 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 were the focal points when designing the M773LW3. Hoses and belts have been eliminated wherever possible to reduce clutter and confusion for the owner. The closed crankcase vent system traps oil vapor emissions keeping the engine room and its 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. This allows for easier maintenance and work in the future without having to remove it from the vessel.

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 in all Northern Lights products.

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 total 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.
