Hi AMG,

The different Northern Lights generators recommend oil changes at 200 - 250 hours. The machine is run continuously for 8 -10 days then switched over to the other machine. The nice thing about the murphy pre - alarm is being able to look at the oil and water level without shutting down. That is typical of boats with the same size generators. Often the boat is set up with two different size machines. A smaller machine as a night generator or light load machine. It is also common to have three machines. Two full load and a third as the night generator. Sizing is important. Load is very important for diesel health. The nice thing about a night generator is being able to keep the diesels properly loaded to avoid wet-stacking and glazed pistons. Water cooled load banks can be utilized in boats that need the extra load during low electric usage. Many Westports have water cooled load banks. It is my understanding that Feadship is now installlling load banks as standard equip.
