I recently purchased a used 1994 Four Winns Fling jet boat with a Johnson 115hp turbojet engine. Put it in the water and tried to get it going. It seems to start just fine, but only runs for a few seconds, smokes quite a bit and then stalls out. It sounds ok and doesn't appear to be overheating. Its oil injected. It sort of seems like it's either not getting enough fuel or it is getting too much oil. Does anyone have any ideas about what could be wrong and/or what I could do to remedy the situation?
