If you think that the transom needs work you better look at the rest of the bulk heads and stringers. Even more so if the tank has issues.
The stringers and bulk heads around my tank were completely rotted and had to be replaced and I didn't know that until I pulled the tank or take a really good look at the bulk head in front of the motors. You might be able to check the stringers along the tank there. On my panther there is access in the floor to a small part of the main stringers but when I bought the boat that seemed like it was solid there but I was wrong. I would get a survey and make sure that includes a report on those areas and ask them how they checked it because there is very little access to that area. The pictures are the bulkhead infront of the motors you can see the rott in the stringers and the other is with the floor and the tank out it is hard to tell but there is no wood left in the those stringers or the mid bulk head just mush. I just wanted to warn you that on the old 30 foot scarabs it's very hard to see whats bad untill you tear it apart. The boat is built with inner liner that won't let you get to it to check it out.
Good luck I hope its all good for you and you make a great purchase
