Dimensions subject to change without notice. Contact dealer or visit www.northern-lights.com for most current installation drawings. 1. Based on SAE J1995 and ISO 3046. 2. Actual fuel consumption will vary depending on operating conditions Engine Block Lubrication System • Four cycle, 4 cylinder, liquid cooled, naturally aspirated, overhead valve diesel. • Full ow, spin-on oil lter with bypass. • Swirl combustion chambers improve fuel efciency and reduce smoke. • Glow plugs for quick cold starting. Cooling System • 8.6 qt. (8.2 ltr) oil capacity for better lubrication. 200 hr oil change intervals. • Oil drain for quick, clean oil changes. • Closed crankcase vent system keeps oil vapor inside engine for clean engine room. • Jacket-water cooling system in heat exchanger or keel cooled configuration. Fuel System • One-piece heat exchanger housing, expansion tank and liquid cooled exhaust manifold. Fewer troublesome hoses and gaskets. Cast iron to resist corrosion and electrolysis. • Fuel system is self-venting. • Keel cooling configuration is standard • Injection pump with 5% mechanical governor for close AC frequency control. • Pintle injectors with replaceable tips. • Heat exchanger cooling is optional. Cupro-nickel, tube-type heat exchanger element can be removed for easy cleaning. Easily accessible, rubber impeller seawater pump of bronze and stainless steel is gear driven; no pump drive belts to fail. Cast-iron wet exhaust elbow is included. • Northern Lights, direct coupled, brushless AC generator is maintenance free. 12 lead design is reconnectable for 1 or 3 phase, 60 Hz output. Conservative heat rise rating: 95°C/50°C ambient. • Automatic Voltage Regulator (AVR) is powered by dedicated AC winding for true 300% short circuit capability. Quick ±1% RMS no load to full load voltage regulation. AVR has circuit breaker protection. • Generator features high quality Class “H” epoxy insulation, accessible diodes, over-sized bearing and junction box for wiring. • Mechanical lift pump with hand primer. No electric pump to fail. • Large spin-on fuel lter. • Stop solenoid controls the fuel rack, not throttle, to eliminate speed variance and linkage problems. • DC system uses reliable relays instead of unrepairable printed circuit board. • 12 volt starter motor and battery charging alternator with regulator and belt guard. • Standard panel: Remote mount S-3C has hour and volt meters, oil pressure and coolant temperature gauges, stop-start switch and preheat switch. • 20 foot (6 m) plug-in panel harness lets you mount your panel anywhere on board. DC system is expandable to six panels up to 110 feet from the set. • Meets US EPA Tier II emission requirements for a cleaner environment. • Low oil pressure and high coolant temperature shutdowns are standard. Special Equipment • 1 1/2 inch NPT exhaust outlet. • Rigid welded steel base frame. • Four plateform mounts isolate vibration. • Tough gray enamel paint for long life finish. www.northern-lights.com Dealer • Operator’s and parts manuals standard.
