buying old boat

I may buy an old boat to use for 1 season I found a '84 mastercraft boat is in good shape yet does not have any seats. it looks like someone either took good care of it or was going to restore it. I was planning on putting one of those ballast seats in the back and making new seats in the front. no big deal I ride behind my buddys 00 malibu vdrive yet I want to go everyday and he goes once a week. I will buy a sport nautique or a 210 in a year or so but was wanting to know how the old mastercrafts do for wakeboarding I tried a search and found nothing thanks for input is there a old boat buyers guide?
