On my 33-2 i was able to disasemble and rebed port side, but on starboard, the bolts are welded in corrosion from the aluminium backing plate. I tried various techniques ( with Dave advice) but gave up before i damage something. Would have like to inspect, clean and rebed but with sealant added on deck it does not leak.
On my boat the deck was sealed with putty, no balsa core exposed. Moisture readings are dry. Good luck but be careful with thèse bronze bolts. Like Dave said.

I won’t try to describe it but you remove the bolts, the top plate (and bottom if you wish) clean both up, (I polished mine, couldn’t help myself) clean up the deck and rebed with butyl. It was done with butyl from the factory, so maintenance is a breeze, and it should be easy to remove the bolts by tapping from below with a mallet. I do not believe they are welded to the plate - 99% sure. You can also separate the deck fitting from the deck by tapping in a thin wedge a small amount - then wait - then tap again. Then wait. I use a thin, sharp putty knife to start. Then switch sides, then wait. The butyl is elastic and comes apart slowly, give it time. Patience is your friend. If more force is require to tap the bolts, reinstall the nuts in reverse but don’t tighten them. Tap on the nut not the bolt. Be careful though- if you really go to town you’ll learn about cold welding of stainless. (Shouldn’t require that in this case). Good luck. If no wise guy used 5200 or similar in the past it should be an easy job. Dave (33-2 with one chainplate re-bedded a few years ago.)

I think you have corrosion between the bolts and the aluminum backing plate. At least I'm guessing the backing plate is aluminum. You might try penetrating oil for several days. Good luck.

Please help me understand how they are fastened. I have undone the cabin-side nuts on the 4 bolts, but they are resisting my efforts to withdraw the bolts from the deck-side, where the bolts have round heads. A socket wrench on the cabin-side nuts unscrewed them easily without needing a wrench on the deck-side. Are the bolts welded to the covers? To lift the cover without damage to cover or boat: Do you hammer on the bolts from below? Do you lever the covers up from the deck side?
