So the boat ran great over the week in Mizzou until the last day. It runs great up until about 2800 rpm's and then cuts out to like 2300, then runs right back up to 2800. It almost sounds like a rev limiter. It starts great and cruises around fine as long as you stay around 2500 rpms. We checked the vaccum lines and fixed one small leak on a plug, but that didn't do anything. Also thought it might be bad gas so we added a few gallons and put some treatment in there to dry it out if there was water in it. Also changed the low pressure filter and drained the water separator. Any ideas?
