![]() Thats why the genset repair business is very good in the Caribbean and other tropical areas. If either temperature were higher (such as 95 ambient in an engine compartment and 78 water in the tropics), the performance would deteriorate. The workshop provided very advantageous conditions for gensets: Ambient air temperature of 56 and cooling water at a constant 42. It happens to be directly under our second-floor office. Our own test site was the workshop of Dan Kerrs Kiwi Marine Services in the Ted Hood Marine Center in Portsmouth, Rhode Island. In the case of Westerbeke, the figures produced by the tests run by Westerbeke personnel can be compared with those we obtained in our testing of other makes. Instead, they offered to supply us with their own test data, but despite several reminders, it was never received.īecause both Westerbeke and Onan are prominent in the diesel genset business, basic data about their 8 kW units are included in the chart on page 14 and a short report on the testing we observed at Westerbekes plant in Avon, Massachusetts is on page 17. Another big manufacturer, Onan, also declined. After initially declining to participate, Westerbeke offered a session at their own test facility in Massachusetts, with the testing set up to specifications like those used in the Practical Sailor bench test. Included in our bench tests were Fischer Panda, Kilo-Pak, Kohler, Mase and Northern Lights. So the list was pared first to diesel-powered sets, then to those in the 8 kW range (the size most commonly installed on 40-50′ sailboats), then to seven manufacturers. Obviously, some pruning was necessary…if the test results were to be published before the Millennium excitement starts. To test that many would be a monumental undertaking involving about $275,000 worth of gensets. The original Market Scan included six gasoline-powered and 26 diesel-powered gensets. Readers wrote that theyd like to see actual tests. Either way, the results varied and positions changed depending on the size (output) of the 32 gensets. Because this is heavy equipment and weight aboard is always a factor, pounds per kilowatt also was calculated. For the gensets, it was purchase price dollars per kilowatt. The intent is to determine which brands and models offer the best value. The report was of the type we call a Market Scan, in which, to make recommendations for a given type of equipment, we laboriously assemble, review and examine features, specifications and prices. Tested to meet criteria for outboard engine boats.An article in the June, 1997 issue about small gensets struck a chord with readers. The AVR protected by a dedicated circuit breaker.Īdditional Options: Ignition Protected Option. ![]() Our automatic voltage regulator gives you ☑% voltage regulation. Low oil pressure, high coolant temperature and high exhaust temperature safety shutdowns standard.ĪC 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☌/50☌ ambient. Gauges include oil pressure, coolant temperture and DC Voltage. Oil drain hose with valve plumbed to base pan as standard.ĭC Electrical System: The DC System features a 12 volt starter motor and battery charging alternator with belt guard. 8.6 qt (8.2 ltr) oil capacity for better lubrication and 200 hour oil change intervals. Lubrication System: The closed crankcase vent system traps oil vapor and keeps engine room clean. The wet exhaust elbow is stainless steel. Its cast aluminum intake manifold with Sound Maze system reduces noise, and its washable air cleaner makes routine maintenance simple. Intake and Exhaust: The M844LW3G meets US EPA Tier III emission standards. The fuel lift pump is mechanical with a hand primer, eliminating electronic pump failures. Stop solenoid acts directly on the fuel rack eliminating linkage problems. The bronze and stainless steel seawater pump with rubber impeller is gear driven, eliminating a potential failure point.įuel System: The self-venting fuel system features an inline injection pump with 3-5% mechanical governor for close AC frequency control. Copper-nickel, tube-type heat exchanger has removable rubber end caps for easy cleaning, and no need for zincs. Swirl combustion chambers improve fuel efficiency and reduce smokeĬooling System: Standard heat exchanger cooling with optional keel cooling. Engine Block: Four cycle, 4 cylinder, liquid cooled, naturally aspirated, overhead valve diesel with glow plugs for quick starting.
