The M1066 Series marine generator sets are powered by new, US EPA Tier II compliant, Lugger diesels. Each incorpo-rates new features that add high power density to the Northern Lights reputation for cast-iron reliability, simplicity and durability.

An Important Decision.

Whether you are building a new yacht or repowering, your future enjoyment depends on the generator set you choose today. It will run day and night, so smooth, quiet operation, long engine life, and fuel consumption are major considerations.

With so much depending on your new set, it pays to choose one that is built up to a high standard of quality; not down to a low price. It pays to choose Northern Lights.

The Heritage Continues.

Four decades of marine experience stands behind every Northern Lights.

Yachtsmen like you, have made them standard equipment on yachts from the world’s premier builders. Service is handled by an international dealer group with assistance from factory branches.

Selection Without Compromise.

Underloaded and overloaded genera-tors cause problems and waste money.

With five models from 80 to185 kW, there is a M1066, 60 or 50 hertz set that is just the right size for your vessel.

Multiple Set Power Teams.

Northern Lights broad range, 5 to 520 kW, lets you combine multiple sets aboard your vessel. Use two M1066s to simplify maintenance and parts supplies. A smaller unit can be a night set. Mix and match sets for the best, single source power solution.

Silky Smooth and Whisper Quiet.

Noise and vibration abatement is a top

Northern Lights priority. All M1066s have crankshaft vibration dampers. Standard equipment hydrolastic mounts isolate 98% of set vibration from your hull. A cast valve cover absorbs valve clatter and traps crankcase oil vapor for a clean engine room. The cast iron, fresh water cooled exhaust manifold absorbs combustion noise. Choose a Northern Lights super attenuated enclosure with InSep exhaust system to lower sound levels even more.

Advanced Simplicity.

Simple to operate and maintain. Hoses, gaskets and belts have been minimized.

DC control panels keep you in touch with your set’s performance while safety shut-downs protect it. Special 500 hour oil changes, oil drains, one side service and owners manuals simplify maintenance.

Tough Lugger Diesels.

Built for continuous duty, many Lugger powered sets have logged over 30,000 hours without a rebuild. A M1066 has the features to continue this tradition of reliability. From replaceable wet cylinder liners to liquid cooled turbos, cupro-nickel

Features that will separate your set fro

Engine Block

• Lugger six cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesel based on heavy-duty industrial engine block.

• Balanced, forged crankshaft with induction hardend journals and rolled fillets. • Bimetal-lic valves have chrome stems and rotators.

• Replacable valve seats and guides. • Three ring aluminum alloy pistons with Ni-Resist insert for the top ring. Keystone piston ring reduces carbon buildup under light loads.

• Torsional crankshaft vibration damper for smooth operation. • Eight groove, poly-vee drive belt powers the DC alternator and

• Electronic controls. Waterproof module protects engine control unit for electronic fuel injection and Engine System Profiler (ESP) on all M1066 models.

M1066 Series freshwater coolant system pump.

• Replaceable, wet cylinder liners for long life and low rebuild costs.

Fuel System

• Direct fuel injection systems (see feature box)

• Ring clamp fuel filter with air bleed and drain. • Diaphragm-type, mechanically driven fuel transfer pump with manual priming lever. Electric fuel transfer pump on “A2, A3”. • Flexible fuel lines routed to fuel manifold on base frame for easy installation of vessel’s hard piping.

Lubrication System

• 500 hour oil change with special require-ments. • Positive displacement gear-type oil pump. • Full flow, spin-on oil filter. • Oil spray cooling reduces piston crown temperature for longer life. • Freshwater, plate-type, full flow oil cooler reduces heat and thermal breakdown of lube oil. • Large capacity oil pan. • Cast aluminum rocker arm cover traps valve noise and acts as a closed loop crank-case vent to keep oil vapor in the engine.

• Lube oil drain for quick oil changes.

Freshwater Cooling System

• Two thermostats for safety and quicker warm-ups.• Heat exchanger cooling includes: Gear driven, flexible impeller seawater pump. Easy to clean, tube-type heat exchanger is cupro-nickel for long life. • Cast iron, expansion tank with brass filler neck for easy filling. • Cast-iron exhaust manifold has double pass freshwa-ter flow for even temperature control, fast warm-up and no hot spots. • Zinc anode electrolysis protection. • M1066T available in keel cooled configuration.

Air System-Turbocharger-Aftercooler

• “A1, A2, A3, H” models have aftercooler with aircraft quality, 70/30 cupro-nickel, two pass element (1). Oval water tubes are easy to clean and stronger than round tubes.

Corrugated air cooling fin design supports tubes better than plate fin type. Seawater piping (3) is cast bronze and stainless steel.

Water never touches the cast aluminum air ducts (2). No gaskets; all components are machined and have o-ring seals. Seawater direct from the pump for maximum cooling.

Dry bolt holes protect cylinders.

M1066T, M1066A1, A2, A3: Electronically controlled rotary fuel injection pump for higher injection pressures, variable timing control and precise fuel metering. Higher power with lower emissions. • Two valves per cylinder.

M1066H: High-pressure common rail (HPCR) fuel injection system for high output, improved fuel economy, better load response and low emissions. HPCR continuously supplies injectors with highly pressurized fuel. Higher pressure means better fuel atomization. Injectors are electronically operated by an engine control unit giving nearly infinite control of fuel quantity, injection timing and multiple injection events per power cycle. Pilot injection reduces cold start smoke and noise. • Four valves per cylinder give increased air flow and allow injectors to be centered in the cylinder for an optimal spray pattern. • Stainless steel exhaust port liners control heat rejection to head.

heat exchangers to gear driven seawater pumps. Rugged components built from the finest materials.

Aftercooled For High Power Density.

A Northern Lights exclusive. No other set builder has aftercooled this engine! All “A” and “H” models have an aftercooler that cools the intake air. Cool air has more oxygen for better combustion. This after-cooler, along with electronically controlled fuel injection, give you more kW output.

Electronic System Profiler.

“ESP” is a window to your set’s real time operating condition. The ECU that controls the electronic fuel injection produces a SAE J1939 data stream of engine information that can be shown on an optional CANBUSS monitor panel.

Superior PMG Generator Ends.

Northern Lights meet ABS and Lloyd’s standards. All have low 95°/50° tempera-ture rise ratings and ±0.5% voltage regulation. All M1066s have Permanent Magnet Generators for 300% short circuit capability required for classed vessels.

Complete Options List Each option is designed to integrate into a total power system custom built for your vessel. Consider the high HP electric clutch PTO that can supply up to 190 HP of bow-thrusting, deck winching, sail furling hydraulics at a touch of a button.

Complete Unit Testing.

Testing is just one of the quality controls that assure your satisfaction and supports your decision to choose the very best for your yacht–a Northern Lights.
