Initially designed for Alaskan fisherman, Luggers are well known by commercial and pleasure craft operators for their long life and smooth, quiet operation.

The L1064T1 features a mechanical fuel delivery system and liquid cooled turbocharger for enhanced fuel effeciency. Ideal fo rthe commercial operator who runs full-throttle for long periods, the L1064T1 is designed for long hours and simplified maintenance.

All the 1064 diesel engines are US EPA Tier II compliant with an in-line design tht makes them perfect repower engines for older in-line six cylinder machines.

The Lugger 1064 (106 mm bore-4 cylinder), 4.5 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 marinization is cast iron tough. The expansion tank and liquid-cooled exhaust manifold are cast iron. Some engines only use bypass water to cool their manifolds. Lugger integrates the two pass manifold into the cooling system main stream to assure even temperature control and to eliminate hot spots that can stress metal components.

Light-duty, small-displacement diesels operate at speeds up to 4200 rpm. This means high piston speed and short life. Lugger power comes from cubic inch displacement and long stroke design. With a maximum rpm of only 2400 or 2500 and a recommended cruise of 200 rpm less, a higher percentage of the available horsepower is usable. Lower RPM also means less noise and wear, more complete fuel combustion and longer life.



Lugger cylinder liners are surrounded by coolant for better heat dissipation. The liners are replaceable to reduce overhaul costs. Unlike “linerless” throwaways, a Lugger can be rebuilt in the boat.

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. 1064s have two counter-rotating balancing shafts to provide smooth operation.

Direct injection, long stroke and precise fuel metering all add up to excellent fuel economy.

That’s why the pipes, hoses, belts and gaskets that cause problems on other engines have been engineered away. This makes Luggers easy to maintain too. Service points are on one side for easy access and the in-line design gives you elbow room in the engine room.

The full line of options and accessories lets you design an engine that is custom built to match your vessel’s needs. With an optional front power-take-off your Lugger can power your vessel’s hydraulic auxiliary systems. It’s more than an engine, your L1064 is 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.
