Four cycle, 4 cylinder, liquid cooled, naturally aspirated, overhead valve diesel with glow plugs for quick starting. Swirl combustion chambers improve fuel efficiency and reduce smoke.

Standard heat exchanger cooling with optional keel cooling. Copper-nickel, tubetype heat exchanger has removable rubber end caps for easy cleaning, and no need for zincs. The bronze and stainless steel seawater pump with rubber impeller is gear driven, eliminating a potential failure point.

The self-venting fuel system features an inline injection pump with 3-5% mechanical governor for close AC frequency control. Stop solenoid acts directly on the fuel rack eliminating linkage problems. The fuel lift pump is mechanical with a hand primer, eliminating electronic pump failures.

The M844DW3G meets US EPA Tier III at 60 Hz and IMO Tier II at 50 Hz emission standards. Its cast aluminum intake manifold with Sound Maze system reduces noise, and its washable air cleaner makes routine maintenance simple. The wet exhaust elbow is stainless steel.

The closed crankcase vent system traps oil vapor and keeps engine room clean. 8.6 qt (8.2 ltr) oil capacity for better lubrication and 200 hour oil change intervals. Oil drain hose with valve plumbed to base pan as standard.

The DC System features a 12 volt starter motor and battery charging alternator with belt guard. Gauges include oil pressure, coolant temperture and DC Voltage. Low oil pressure, high coolant temperature and high exhaust temperature safety shutdowns standard.

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 automatic voltage regulator gives you ±1% voltage regulation. The AVR protected by a dedicated circuit breaker.
