Engine doesn't rev over 3000 rpm when under load

I have a problem with my 96 pro star 190 engine. When under load the engine doesn't rev over 3000 rpm. When I put it out of gear and rec it up no problem. I changed the fuel filter and took the air filter off. Does anybody had the same experience? What could that be?

I assume you have checked to make sure your perfect pass isn't engaged?

In my experience it was due to low fuel pressure. Does yours have an in-tank fuel pump?

No. I just had a thought the other day I ran it very low with the gas. Could it be that I sucked up dirt in the fuel pump?

If it started acting up after running low on gas, check the inlet screen at the pump inlet line.
Easiest way is to turn off gas valve at top of gas tank, remove pump from engine to check the screen. Mine was very dirty last year, boat would not get on plane.

Found different thread where somebody wrote that. So this afternoon I did that and it was very dirty. But thank you very much for that hint. Runs great good again
