Iwas out on the weekend and was having trouble with my motor it wouldnt idle on low and then started running rough, so we headed back to shore on the way back the boat sputtered and the stoped dead, turned everything off and it re started but didnt sound right? so i pulled it on the trailer and checked the plugs and commpression. cyln #1,2,3 all checked out with wet plugs and compression of around 125 #4 dry plug no compression? what next, and how much could this cost to fix?

thanks kevin
