Features & Benefits

Engine Block: Four cycle, 4 cylinder, liquid cooled, naturally aspirated, overhead valve diesel with glow plugs for quick starting. The forged carbon-steel crankshaft is stronger than cast iron while the cross flow head makes for efficient combustion. Helical cut gear train reduces noise.

Cooling System: Standard heat exchanger cooling with optional keel cooling. Copper-nickel, tube-type heat exchanger has removable end caps for easy cleaning. Electrolysis protection via zinc anode. The bronze and stainless steel seawater pump with rubber impeller is gear driven, eliminating a potential failure point.

Fuel System: The self-venting fuel system features an inline injection pump with 3-5% mechanical governor for close AC frequency control. The fuel lift pump is mechanical with a hand primer, eliminating electronic pump failures.

Intake and Exhaust: The M944W3FG has a stainless steel wet exhaust elbow.

Lubrication System: The closed crankcase vent system traps oil vapor and keeps engine room clean. 10.5 qt (10 ltr) oil capacity for better lubrication and 250 hour oil change intervals. Oil drain hose with valve plumbed to base pan as standard.

DC Electrical System: The DC System features a 12 volt starter motor and battery charging alternator with belt guard. The set is equipped with a standard remote mount control panel, featuring an hour meter, stop-start switch, engine gauges, a preheat switch, and includes a 20 foot (6m) harness. The standard panel can be expanded to six panels, up to 110 feet from the set. Gauges include oil pressure, coolant temperture and DC Voltage. Low oil pressure, high coolant temperature and high exhaust temperature safety shutdowns standard.

AC Generator: The Northern Lights, direct coupled, four pole, four lead generator has Class “H” insulation, a pre-lubricated bearing and features a conservative heat rise rating of 95°C/50°C ambient. Our external automatic voltage regulator is powered by a dedicated AC winding for true 300% short circuit protection.
