I have a newly rebuilt Mercury 200 efi (3.0) and when I leave my boathouse, I idle for about 400 yards to the river channel. I then trim in and give it gas, and the engine just bogs at about 2000 rpm for about 1/4 mile before taking off with a good holeshot. It may run a little rough for the first 15 seconds and then runs great. I can fish all day without any other problems. One of my fair boat mechanics here suggested replacing the computer, but that is an expensive guess. Got any suggestions? Thanks
