1974 20' SF - Potential Purchase

[GWTHedman]

Afternoon-
Longtime lurker who is hopefully going to finally own a SeaCraft. Looking at a 1974 20' on Cape Cod. Current owner restored from hull up, raised deck 2", full transom, fabricated a fiberglass bracket, new tank, etc. Powered by a 1998 Yamaha 130 2S. On the surface all of his work seems to be top notch. Trailer is rock solid with new tires and LED lighting Sea trial won't be until the end of the week. Anybody on here know anything about this particular restoration? Any thoughts on what I should be looking out for? Lastly, any recommendations on a local knowledgeable member / surveyor who could assess the boat?
Not sure if the photos will come through sized correctly, haven't quite figured that out yet!
Thank you in advance-
Gary
