1976 Carver Mariner 3396 - Soft Decks

[BoatinginFL]

I'm a new owner of this boat and new to boating in general. I grew up in CO but gave up the mountains for the waters of FL. My boat has a soft deck in the bow area and also the port stern under the cleat. The wood looks pretty rotted in both areas. I've read a lot about drill and fill epoxy repairs. Will this work well in these areas? Any advise on better methods? Thank you
