I have an '87 Pro-v 150 that is slow to plane and seems to bog down after a few minutes out. The shop called me today to tell me that upon starting to check it out, I have one cylinder that is weaker than the rest by 10 psi. (5 at 101 and 1 at 91). They seemed to have a bleak outlook for it, but what are my options without sinking a fortune in this engine? If I have to get it re-built, what is the general cost? Thanks in advance for any help.
