Big Power in a Small Package

nnA tireless little powerhouse, the L844D can power the smaller sized vessel, with the same reliability, durability and simplicity that have been hallmarks of the Lugger product lines for decades.
The L844D produces 40 horse power at 2800 rpm, or 30 horse power at 2500 rpm. Built to the rigorous speci cation of Luggers custom marinization process, the L844D features an impressive power-to-weight ratio and highly ef cient fuel consumption. The L844D is certi ed to meet current emission regulations. Like all Lugger engines, it is highly customizable, and known for a commonality of parts; providing for a remarkably exible and adaptable marine propulsion unit.
Mechanically injected and naturally aspirated, the L844D is designed for maximum simplicity in a technologically advanced nn

nnpackage. To reduce troublesome gaskets and hoses, the L844DҒs cast iron manifold, expansion tank and heat exchanger are combined into a single component system. Other service features of the L844D are designed with the recreational boater in mind. The raw water pump is located to make impeller changes a breeze, and it is gear driven, eliminating the pump drive belt. Most service points are grouped on a single side to further aid in service. The two valve per cylinder design provides for maximum air ow in a compact space. The L844D features swirl combustion chambers to reduce smoke and further improve fuel ef ciency. The DC Logic electrical system continuously controls and monitors vital engine functions. By combining the world renowned technology of Northern Lights engineering, with an eye toward the simplicity and ef ciency required by small vessel operators, the L844D produces quality marine propulsion in a small and economical package.
Lugger engines by Northern Lights feature many components for outstanding performance and cost ef ciency. Recognized world wide as the most reliable and durable marine engines, Lugger delivers the highest quality engines on the water.

The L844D 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. Northern Lights is so dedicated to the principals of customization and ease of use, that the L844D comes available with left or right handed dipsticks. >
