I bought a 2005 mercury 9.9 pro kicker. It starts fine but runs rough for approximately 15 minutes and the red low oil pressure light flickers like its grounding out and/or misfiring. After 15 or so minutes it runs fine and the light no longer comes on, I ran it for about 4 hours the other day with no issues. It has 130 psi in both cylinders, oil was recently changed and is full. I have not done an oil pressure check yet.
Has anyone had an issue like this before?
