Dave, at first I thought, whoa, almost $20K is way too much...until I went back and read '14 Zuke 250. So let's assume he got the motor and rigging for $12.5K, that puts the boat and trailer at $7300. Now if we would go back and throw the old OMC 225 on her, you'd be looking at around $10K for the package.
So $19,850 to me is an excellent price! And in answer to your question regarding the hull, no real problems with her, maybe some soft spots in the cockpit sole...
