My biggest fear is that when the teak is removed the ply sub-deck will get very weak and floppy, which would mean I'd have to renew the rotten ply core : that could esculate the job into a major deck rebuild costing $$$ and taking months to complete.
I hadn't realised that most of the ply core will be wet because of water perculating down through the screw holes, and after 40 years will be in a very bad state.
Your cores look like they were in very good condition: impressive build quality!
