What to look for in an '83 V20

I have found a 1983 V20 Fisherman w/ an 87 Evinrude 150hp down the street from me. *Asking price is $3900. *I'd like to keep the boat for a couple years and then repower when Evinrude has a couple years on the V6 Etecs that are coming out later this year (or so I've heard). *What type of things should I look for w/ this year boat, aside from tapping the stringers? *Are there any specific problems I should look for? *Does this sound like a good price? *I'm not 100% sure what condition the motor is in, but the boat looks good. *The one problem is that it has bottom paint that would not be needed as I plan on trailering it. *Is that hard to remove and can the dull finish be brought back to life?
