Last week we started developing an issue with the check engine light coming on when we brought the boat back to idle after a ski run. Initially it would flicker. Eventually it just started to stay on. Turn the engine off and back on- everything was fine. Oil pressure did read a little low at around 20 at idle around 40 under power. Today we had the same issue. The only thing that was different is the the engine kicked into limp mode while running under power for about 2 minutes even though the check engine light didn’t come on. Seems like it probably is an oil pressure sensor issue. The only thing that throws me is what happened today. Am I missing something?
