Boat sunk

First is the day I bought it. 3 years ago. Second was my nightmare. I'm now out of denial and trying to decide the big issue. Take two years and couple of 1000 $ and do everything myself. Motor runs great? I don't get it. If I was was in salt water for 5 days. I would puck pistons all over the place. I 'm going to get hold of the guy that redid the 83 and start collecting information for the job. Start with all the the sites and start the process of scronging parts and equipment to put it all together again. Transom and stringers are a must.
