Sorry for the confusion. The pvc was not permanent. I pulled the pvc before the epoxy fully hardened. I used it as displacement for the epoxy - just to use less epoxy and so it wouldn't set as fast (the bigger your epoxy batch the faster it cures), and allow for better seeping into the wood. In retrospect I could have taped off the bottom and just filled it with a thicker epoxy mix, let it set and then drill. It probably would have been easier to drill rather than having a hollow center.

Yours looks much like mine one good one kind of bad... one of my blocks was pretty bad and you could see a stream running down the stringer from the block while at rest in the water. It sucked up a lot of epoxy before sealing the wood. The epoxy serves to reconnect and seal the the hull to the block to the deck. probably, Theoretically, if properly sealed you would even need the tubes.

One more thing, I would use 4200 or 5200. I'm not sure silicone has any place in this equation in fact, their combined chemistry may be detrimental to one another. I used 4200 because I know somewhere down the road this will be required again...
Hope I clarified that.

Just adding to MG statement.

Silicone sealant is a gasket material---Period. Silicone depends upon mechanical compression to maintain its seal. Not a good choice for this application
