The standard L944D electrical system is a technological standard-bearer, with a 12 volt grounded system standard, and 24 volt available Electrical System > The L944D uses a gear-type, high capacity oil pump with a lube oil cooler and a full ow ltration system. This technology lters particles large and small from the oil ow in a single unit. Lubrication System > HORSEPOWER Air System The L944D is designed to meet Current USEPA Tier II emission standards. Its air and ventilation systems are built to run as ef ciency and cleanly as possible. The closed circuit crankcase vent traps oil vapors to keep the engine room and environment clean. The cast-iron wet exhaust elbow is unique in the marketplace and comes standard. > 4 2 9 1 8 10 3 4 6 11 5 7 The L944D combines the tradition of Northern Lights engineering excellence with the advances of modern technology. The fuel system is mechanically controlled, allowing for smooth, ef cient horsepower in a package that wont cramp your engine room. Fuel System 5. Gear driven, rubber impeller, seawater pump. Bronze and stainless steel. No belt. Mechanical seals.6. Spin-on oil & fuel lters. 7. Oil drain for quick changes. 8. Removable heat exchanger end covers for easy core cleaning. 1. Cast Iron two pass exhaust manifold. 2. Cast air intake silencer with washable air lter reduces air intake noise. Crankcase oil vapor trap for clean air.3. Bosch type inline injection pump. 4. Top & side oil lls. 9. Jacket water cooled with one piece, cast iron expansion tank. 10. Cast iron wet exhaust elbow w/ temp switch. 11. 12 volt DC starter and battery charging alternator. Northern Lights engineering has produced an engine with a minimal amount of leak or breakage points. This leads to a cooling system that is uniquely designed for the rigors of the marine environment. Reliable and ef cient cooling is built in to the L944D, thanks to its single-piece cast iron exhaust manifold. Cooling System > As a base engine in a small vessel, or a wing engine in a larger one, the L944D is built to be driven hard over the long haul. as an option. The battery charging alternator and starter come standard, as does the control panel featuring tachometer, hourmeter, coolant temperature meter, DC voltage meter, oil pressure gauge and key switch. >
