you had it in the water yet bud? if its not to late, you might aughta before you pull it. sometimes those things run great on the muffs, then when you put them in the water they fall flat on thier a$$. also, you can get a compression guage at autozone for about $15 remove all the plugs and open up the throttle wide open. check each cylinder with the guage by turning over with the key (make sure battery is fully charged) if it all checks good talk to macoejoe. this may be a better deal than the one he is looking at. if mj dont want it post that puppy on ebay, no reserve, and start the bidding at $500. if it all cheks out good you should get $800-$1000 for that motor! good luck.
