I guess you are talking about an Explorer 24.
If so it has the sea V hull and I've never read anything about a bad year for a grady on this site.
You should get plenty response on this topic.
I have a 91 dolphin 25, pre sea V hull and it rides great no problems at all. Grady is a very well made boat you should have no problems. I recommend getting it surveyed before you buy if you have not already.
I have a 24ft 1994 Explorer with hardtop. Had a Yamaha 250hp and now have a Yamaha 300 HPDI pushing her. Notched transom.
Good boat, good ride. I fish, both bay and ocean in NJ.
