First opportunity actually get the boat out and run yesterday. Five people, nearly full tank and plenty of beer. Had some storms come up so I decided to run south to get away and when I powered up I noticed the port engine was producing more RPM's than the starboard. Did the tach tap, several times at different levels and nothing. Even at 7-8 MPH it was two hundred higher. Second thing was the port engine seemed to be louder than the starboard. Ideas on where to start?
