Looking for first boat. Considering a 1996 Chaparral 1930. It's in good cosmetic shape and has around 150 hours (per seller, but no meter, so is probably a bit more). My mechanic looked at it and said good overall shape and good compression on engine but it may need new gimbel bearing. And, if water/rust present, additional work on top of that. Seller wants 7500 for boat. I'm wondering if I need to negotiate further; buy it and suck up the cost of repair; or run from the boat. Thanks.
