Looking for advice. I just received the results of an engine inspection; the boat has a 502 with just under 800 hours. The leak down test results are as follows from cylinder 1-8: 14%, 15%, 20% 74%, 57%, 38%, 20%, 25%. I understand that 10-15 is good and normal and 74% is less than ideal (bad). I guess my question to you all is this something that could get a top end refresh for a few more years of use or is this really the end of life and in need or a rebuild. The engine starts and idles well, seems to get up from say 2,000-4,000 rpms, and the boat seemed to get to 4,600 rpms on the water without hesitation.
