Thinking about buying a 1973 Seafari?

[Seaman]

Newbie here looking at buying my first boat. A guy down the road has a 1973, 20' Seafari O.B.. Have yet to inspect it close up and I have only driven by it and called him about what it needs. I must say it is in beautiful cond. and he claims it needs nothing. The OB has apparently been rebuilt.

As this is my first time shopping for a used boat are there any pointers to what I should look for, tests I can perform, questions to ask, rea$onable price if all check$ out, etc, etc.

All advice would be greatly appreciated. And if I do by the boat, I vow to do a complete write-up with pics.
Thanks, Seaman
