Went to the boat this past week to change oil and filters in both engines; main and Genset. Getting ready for some fall/winter cruising, weather permitting. Need to figure out why the Genset shuts down after a few minutes of running. Seems to be a fuel issue. Main runs just fine. New fuel filters, new sea water impeller. Starts and runs great, but for just a few minutes. I suspect it is a fuel pump issue. Another puzzle to sort through. I have a service manual for the main engine, but not the Genset. Need to get my hands on one. Cummins has them on a PDF file for a fee.
