Hey guys, total newbie here with a couple of questions about my 25 hp merc. Motor starts and ran fairly well but did have a rough idle. I took it to my local boat dealer for inspection and was told the top cylinder carried 125 pounds of compression while the bottom cylinder only carried 77 pounds. I haven't pulled the motor apart yet but was just wondering what my options are. Dealer wants $1100 for the powerhead not including installation. What other powerheads will fit this motor and where could I get one? I hate to go used but I don't want to tie up $1000 in a $1200 motor. Also, do you think if the cylinder walls aren't scarred, that i could possibly put another ring in it? I know I probably shouldn't be asking the questions until i tear it down but just figured I'd ask you guys before possibly wasting my time. I was actually getting ready to sell the motor before all this happened but obviously not going to do that now until it's right. I hate to part it out because the motor looks almost new. Any help would be appreciated. Thanks in advance.
