I have 580 total hours on the boat. I have new AC MR43T plugs, new Pertronix ignition, rotor button, distributor cap, carb fuel filter, fuel water seperator. Boat cranks cold and runs fine. Choke does pull open and stay open at about 150 degrees ( quadrajet). After running at 3k rpm for about 20-30 minutes from the slip, when I idle around for 3-5 minutes or just cut it off for few minutes it skips bad until it plains out at around 3k rpm. It definitely skips like it is electrical ( plug wires or coil)is all that's left.<br />I thought someone might have been here before and could recommend wires and coil.<br />Thanks,<br />Nick

Next time it's Skipping,.........<br />Start pulling the plug wires off, 1 at a time, til you Find the 1 that's Not Firing......
