Out running today, trying to keep up with Excursion and ended up idleing back to the dock. Starboard motor shut down and sounded pretty bad when we got it running. Pulled the plugs and 3rd one back on the right side didn't look to good. A couple of the guys with me today may have a better idea if this might be my only problem????

When you say third one back, do you mean facing front or back, if its #6 and you have a mpi with a vst set up the diagraghm could be bad in the vst, or it could be a bad plug, plug wire, dist cap. Worst case scenario you burned a piston, check you your compression to find out. Need some more specifics.
