I have a 1985 Mercruiser 140hp. I just recentley had a $600 tune up on the engine, which included spark plugs, wires, cap, rotor and a couple of other misc stuff. The engine starts up fine. As soon as I try to get up to 4200rpm it starts to surg and hesitate. I keep it under 2000rpm it runs fine. I need help. Thank you.
