Going to check out a '93 tomorrow

If those numbers are in fact correct, It would certainly play into the bargaining. Especially at that asking price. Better you should do your own compression test as well as a sea trial. Do the compression test after it's warmed up too. I think the $9800 was a reasonable price range to be in leaving room to bargain. But if one cylinder is bad and you're looking at a $1200 power head rebuild, then it's a different ball game.
It may not turn out as bad as you'd think. A real nice boat for the right price would be worth a lot of family enjoyment. ;)
