Our new-to-us '84 Fu Hwa has Teak decks, but I do not recall whether it's screwed and bunged. I'm rebuilding the lazarette hatch which was Teak glued down to 3/8" scraps of wood and that glued to 3/8" of fir plywood which was visible when the hatch was open. There were steel staples applied for clamping. There were no screws. The glue was polyester resin.
Since the 32-year-old Teak is in good shape and matches the rest of the boat, I demolished the rotted and ill-repaired plywood while retaining the Teak glued together with the seam sealant.
The remaining Teak is now 'perfectly' clean and ready for whatever I finally choose to replace the 3/4" of rotted plywood. I'm trying to be patient and give the Teak some time to thoroughly dry.
Pictures thus far are below. Before, top; before, bottom; starting demolition of the patches and wondering if the whole thing will simply fall apart; routing the remaining plywood so that it will split out, beginning to grind down (up!) to the Teak; built a platform to hold the potentially loose planks in place; the bottom of the top clean and drying:
