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

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.
