"Hi- I Have a pair of 1996 BF90's on a Sea Cat. The port engine looses RPM's and sputters after the engine warms up. I've swapped all of the electrical comp (i.e. coils, wires, control mod,plugs) from one engine to the other and the problem remains. If I pull the plug wires (one at a time) cylinder # 3 appears to be the dead cyl. Any thoughts on what I should try next, Help rockfish season is in."
