New to here with new boat

Purchased a 16 foot alumacraft last week I believe it’s a 82 mv pro or angler. It had been parked under a pecan tree since no telling how long so everything is rotted. Pulled everything out the best I could and cleaned it up. [/img][/img][/img] I pulled the floor out and replaced the foam as well. It’s a hog hunting and fishing boat so I’m going to bedline the deck and floor and sides with roll on bedliner so everything can be spray hosed off and not hold any smell. And me and my brother are going to paint the outside camo. I added a stall mat to the floor to help with vibration. I had found a pin hole under the floor and was wondering if anyone had any suggestions for it. Also if anyone owns one of these boats can I order a seat and mount it straight to the hinge or do I need a special mount. I also found a small metal sheet that I believe the live well lid but the holes don’t match up.
