Para - for what it's worth to you.......if you're looking at a boat here's my speech:
Take your time, don't rush.... look over the transom very carefully checking for a bunch of things, including
1 - Cracks, and cracks that may have been covered up with gel, paint or other.
2. Swollen transom with the bolts sunk into the transom on either side means it's swollen from water intrusion and soft.
3. Transom bows out or isn't straight.
4. Any work done, any plates, anything that looks like cosmetic cover up.
Soft means water instrusion, and if you find it in one location, likely its spread and worse.
This topic gets me fired up - I've looked at many so called " rock solid " boat ads that turn out to have water intrusion, and " oops, the seller didn't notice" etc. These old V's were built with lots of wood and most have at least some water intrusion somewhere. Looked at several Seacraft's that were listed as rock solid......and were sponges.
New transom done correctly by professional costs around $ 5,000
Then if they find more water instrusion, bad stringers etc it gets ugly ....fast.
Being a bit preachy but just passing on info you may already know.
Best of success to you.
Oh.......and perform the transom test - with boat out of water, and outboard tilted up, press down heavily on the outboard skeg and watch the transom for ANY movement.
Then stand on the skeg and do the same thing - if the transom flexes - it's weak, no matter what anyone tells you - it's weak.
