Exposed stringer foam at transom

[Starling]

Hello all,
I'm about to start tearing into my 89' Tracker 20 soon and noticed that the stringers that extend to the transom are open on top exposing the foam . The boat has been sitting for a while and a little rainwater has been collecting so do you think it's a significant issue? I worry that the foam has absorbed it's fill and I need to remove and replace the foam.
Go easy on me as this is my first owned boat and my first attempt at restoring a boat as well. I'm patient and handy with some common sense so I'm hoping this will serve me well - Along with advise from this form

Consider drilling some inspection holes at the bottom of the stringer with a small hole saw to see state of foam. My experience on older 20 and 23 was that the bottom couple inches was completely saturated but the top was dry. Still a lot of weight when you add up the volume.
Think the holes on top are simply where they pumped in the foam . Both my boats had holes every couple of feet in the top of the stringers where the foam was cut flat .

The rear 10-12" of the stringer tops were open on my 18 sf. Looks like the tops were sawn off. I cut the rear 5-6" aft of the height change to make room for transom replacement.

Thanks guys! That makes me feel much better about that issue.
