Crack near or in transom? - 1991 Seafarer 228g

Hello,
I am looking at purchasing a 1991 Seafarer and this is my second inquiry ( newbie!) to all of you. I am getting the boat surveyed in a few weeks time , but just came across these cracks, Starboard side. just above the switch in the battery compartment. The crack does not look fresh by any stretch and is kind of half way between the main outboard and gunwales. It is pretty big, but is this technically part of the transom and how much concern is this. Everything seems fairly solid on this boat but I am coming from a smaller welded aluminum boat background. I jumped a little on the pod which seemed super solid, but did not do this while observing the crack. It even seems to be in a strange place for a stress fracture, but I am eagerly awaiting your thoughts/opinions.
Thanks!

Thank for the replies so far! It is a bit of a mess back there for sure. The Trim tab power unit is definitely not working and I think a lot of the general filth is spewed hydraulic oil from the unit ( the lid not on is my fault, I was checking it out and didn't re tighten). I just assumed that is where they located the battery switches. I'm not sure what the clamped hose is - I think wash down hose? It is good to know about the screw holes- I did not even give them a second thought, figuring it is not a big deal as it is a covered area.
There doesn't seem to be any softness anywhere, but I am no expert and hopefully the surveyor can shed some light also!

It is difficult buying these older boats that are more affordable and trying to weigh the positives and negatives vs price etc. etc. There are a few good things on this boat like brand new gas tank/ system, but certainly at the end of the day I want a good hull or at least one that is worth fixing if the price is right.
