I have a 1996 115hp mercury tracker motor. It will rev up to 5500 rpm's when in neutral out of water. When I put it in gear and take the pontoon boat out it will only rev up to 2500 rpm's.
I took it to a reliable marine mechanic and I water coming into 2 cylinders. I had a cracked intake gasket and he replaced that. He figured that was the problem, the water was fouling out two cylinders.
I brought it home and winterized it We got it out today, started it at the house, put it in the pond. Well it still does the samething. It wont rev up past 2500rpms You throttle it up halfway and it goes to 2500rpm but once you give it more throttle it stays the same rps and speed.
