Initially designed for Alaskan fishermen, Luggers have always been dependable. Used as prime movers on Northern Lights marine generator sets, they are well known by commercial and pleasure craft owners for long life and smooth, quiet operation. Today, electronically controlled Luggers are adding US EPA Tier II compliance to their reputation for reliability, simplicity and durability.
Lugger 1066 (106 mm bore - 6 cylinder), 6.8 liter diesels have heavy-duty tractor blocks. This high torque design provides a strong foundation; but a marine engine is only as good as its marinization. A Lugger’s expansion tank and liquid-cooled exhaust manifold is cast iron to withstand temperature fluctuations and resist electrolysis. Some engines only use bypass water to cool their exhaust manifolds. Lugger integrates the manifold into the cooling system mainstream. This, and two-pass water flow, assure even temperature control and eliminates hot spots.
Light-duty, small-displacement diesels operate at speeds up to 4200 rpm. This means high piston speed and short life. Lugger power comes from large cubic inch displacement and long stroke design. With less spread between maximum and cruise RPM, a higher percentage of the available horsepower is usable. Lower rpm also means less noise and wear, more complete fuel combustion and longer life.
All L1066s have turbochargers to increase power without resorting to high speed operation. Lugger turbochargers are liquid-cooled for safety.
Need more power? Choose the “A” or “H” models. These have an aftercooler that lowers the temperature of the combustion air. Cool, oxygen rich air gives you more power.
Lugger cylinder liners are surrounded by coolant for better heat dissipation. The liners are replaceable to reduce overhaul costs. Unlike “linerless” throw-aways, a Lugger can be rebuilt in the boat, over and over again.
ECU controlled, direct fuel injection, long stroke and precise fuel metering all add up to excellent fuel economy.
Low RPM Luggers are naturally quiet. No high RPM whine. Just a steady rhythm. A special silencer-filter reduces air intake noise. The cast rocker arm cover reduces valve noise and traps crankcase oil vapors to keep your engine room clean. Quiet and smooth; 1066s have torsional dampeners that decrease engine vibration.
That’s why the pipes, hoses, belts and gaskets common on other engines have been engineered away from Luggers. This makes them easy to maintain too. Service points are on one side of the engine for easy access and the in-line design gives you elbow room in the engine room.
With an optional front power-take-off (PTO), your Lugger can power your vessel’s bow thrusters, roller furling, anchor winches and other hydralic auxiliary systems. It’s more than an engine, it’s a total marine power system.
Every Lugger engine is thoroughly tested and quality controlled before it leaves our factory, to ensure the reliability, durability and quality Luggers are known for.
