Drill into to it into the softest spots and check for rot. If rotted you need to cut the top layer of glass out and remove all rotted balsa. Then replace with new balsa, plywood or composite core and glass back over. If not rotted it could be poor layup that has delaminated in qhich case you could inject resin or replace top layer of glass.

Injectadeck could be an option but i had limited success with it...

Look it up on YouTube. There are numerous videos on the repairs.

I've made repairs to several spongy decks...
Knock around with a plastic ball pein hammer to locate the extent of the rot and mark it out. Use a skill saw set around 1/4" depth cut and cut out the area. Dig out the rot and vacuum/clean out then replace with divinicell or any composite core and use fiberglass resin, west system epoxy or similar. Check the level and build up with fiberglass then epoxy the original deck skin back in place. You'll have to address the 1/8' cut that you made either by fiberglassing or if your in a hurry, use 5200 to fill the gap.
This is how I've done it and has worked out perfectly.
