Sounds a little high to me...the motor at best is worth $1500-$1800. The trailer around $1000 - $1200. This leaves the boat at $12,000-$12,500. I have seen newer 23' CC at a better price with a newer engine. If the boat is immaculate and has tabs, bait tank, good electronics, and other extras it might close on price...I kind of look at boat deals as if I had to re-power it. If you hung a new $15,000 engine on it would it be worth the near $27,000 invested...Not trying to paint a bad picture, but sadly 20 yr old engines do fail or get very costly. If you planning on keeping the boat for a while and intend on repowering offer a few thousand less and negotiate some. Good luck!! You didn't say where it was located. There may b a CP member close by that will take a look with you. Extra eyes are always helpful.
