Looking at a boat with a motor that is an '94 88 SPL Johnson that hasn't been run in probably two years. It has been stored pretty much indoors by someone who has a clue. This is a V4 with cylinder readings as follows #1 130psi with 10% leakdown; #2 125 psi/20%; #3 130 psi/9%;#4 120psi/14% the two low cylinders are not side by side. These were done cold start. It was recommended to retest after adding some "engine tuner," and letting the engine warm to temp (another $80). I have read where the rings can be a little sticky after a few years in storage. I have already commited to retesting as I see this a smaller price than the total overall cost. I am currently getting a decent deal on the boat but factoring in a new motor would negate that. I guess my question is if the results on the leak down come back over 10% should I walk away from this boat? Looking at an $8,600 boat that am paying around $8,000 for. What would you do? Any help is appreciated.
