Boat was running rough this last weekend had a hard time getting on plane and wouldn't break 28mph, I thought maybe due to the fact it was 120+ outside and that there was a lot of gear/people in the boat but upon closer inspection it looks like the spark plugs might be apart of the issue. Pulled the plugs and found the #4 plug to be burned, it looks like the dealer also installed the wrong plugs in the boat LFR6A-11 (gapped at 1.1mm) not the LFR6A (.85mm). Has anyone experienced issues with plugs not waring evenly? The #4 is really burnt, makes me thing something else might be happening with that cylinder. Any thoughts?
