Boat fires up fine and idled great. But once it get up to almost plane af half throttle it starts surging hard. I thought bad fuel so drained the whole tank started fresh, replaced the plugs and wires cleaned the air flow and put a new water fuel separator on it. It did have a melted exhaust flap that was still working but replaced. Had it in 2 separate shops with excellent history of repair but even they couldnt figure it out. Thinking possibly electronic now. Any ideas if this has ever happened to anyone else before?
