A while back I had some problems with my 2000 115hp Tracker Marine cutting out but numerous people on this board suggested that I replace the fuel filter and it made a world of difference. Thanks to all that helped! Although it is running much better now, it's still (and always has been) a little rough right around 3000 rpm. I took my mechanic for a spin and he agreed and thought that the accelerator pump could be dirty or defective. Anybody else have this problem or know what exactly the accelerator pump does?
