Well, it's the middle of the night and I'm supposed to buy a boat in the morning. It's a 93 sylvan pro yukon 15' with a 40 hp merc 2 stroke, also 93. I'm ok with the boat but would like to hear if anyone has experience with this motor. It starts up ok and runs on muffs, but that's about all I know. I'm going to check the compression before I close the deal. I'll post pics if I go through with it!
