Hello all. My generator loses prime when I start it after it sits for a day or two. I have had this problem for 6 years and have tried increasing intake size, larger strainer, removing any 90* elbows, increase intake hose size. In addition, when I go out in rough seas, when I'm rocking and rolling, it loses prime then too. I have replaced my salt water pump as it has run dry because of this. The thru hull fitting ( direct intake-no scoop) is at or a little below the level of the generator and exhaust water muffler. The boat is a 46 Jarvis Newman and generator is a 3 cylinder 8 KW Westerbeke 8 TDB. Any thoughts or suggestions are greatly appreciated.
