I would drill the holes a little bigger, also go to the other side of boat and drill a hole over there, tilt Bow all the way up as high as you can get it and let it drain for a few days. 
The rot stuff that you saw is for rotted wood, not no wood! So I think forget that at this point. 
 
I guess at this point I would fill solid with 5200 and let dry for a few days. It will harden up even under water so this is why I think the best way. 
 
You could also leave the 5200 am little reaccessed and when dry cover with  marine tex for a solid cover. 
 
Thats what I would do I guess, see what else oters come up with. 
 
Good Luck
