Just got this boat and love it, Don't know much about The Terry brand but seems nice, it's a Terry 4.7M 1979 need to get the live wells going but that's about it other than the rear fishing seat
I'd highly recommend you do a thorough examination of the deck, transom, etc Boats of this vintage typically have LOTS of issues with water soaked components below dec
being a 1979, I guarantee that if the hull and support wood are not rotten (highly unlikely) that the plumbing for the livewells is busted and cracked.
most boats require a complete makeover after about 15 years. livewell plumbing plastic hose and fittings degrade after about 15.
