I have a 86 checkmate convincor that needs a new motor. I found a 1998 502 mercruiser with 750 hours on it it has redone heads and the fuel injectors were just gone through. They are asking for 5,500 installed plus my old junk motor with the stainless exhaust manifold and gil exhaust. any feed back on the lifetime of these motors and things to look for would be great
thanks
Chris
