$5300 sounds right on to me with no power. I have a '94 V21 and I paid $6500 with a running Yamaha 150 of the same year. I re-powered with a brand new Yamaha 150 2 stroke because the motor that was on the boat needed carbs cleaned plus I was really really wanting a brand new motor.
The PO had just awlgripped the outer hull, put on a new rub rail, raw water washdown, new transom hatches, new deck inspection plates (epoxied in), new yamaha controls, new yamaha oil tank, among other things. Oh yeah, did I mention he also let the brand new 2005 trailer go with it too?? He basically did all the work I was dreading ;D so I had to buy it.
I had a '72 V20 (and still have

) I was working on and I felt I would be alot better off just selling it and buying the V21 and I'm so glad I did. Nothing against the '72, just a lot of time and money to get it like I wanted it.
Tell me this - if you sell this boat, are you gonna buy another boat? If so what size? If I were you I'd keep it and hang a new motor on it ;D
I'm sure everybody else on this board will agree with that!!!
Here's my V21:
