Stus-List 35-3 Leak

The leaks appears to be directly underneath the stringer.  in fact, if you stick your finger down in the limber hole you can feel the squishiness of the stringer core that is being washed away (i've pulled out little pieces of it).  I'm assuming this foam material indicates the core is inactive.  I've tried several times to completely dry this out by sponging out that void with paper towels or a sponge and then try and feel the trickle, but this hasn't proved very effective.
I spent the winter rebedding portlights, grab rails, etc that were all leaking and had rain water intrusion pretty much licked by launch time.  I am definitely seeing this without rain.  I manually pumped it out, left the boat and came back 24 hours later (no rain, no running the engine) and took a measurment of the water level.  I then pumped it out again and took a bucket and refilled it to where it was when I pumped out - 2.5 gallons.  
Unfortunately, I can't see inside the stringer beyond what I can see looking into the limber hole.  Without cutting into the stringer and removing that foam I don't think I'm going to see the actual leak - unless anyone has some suggestions.

If you are having the volume of water you have described 
accumulating each day you should be able to see the leak.  I would bail and 
then spong out the leak and remove every floorboard or access panel you can so 
that you can see the trickles of water coming in.  All of this is assuming 
that it has not been raining where you are the past week. 
The keel moves a lot when sailing and most keel bolts do seem 
to loosen with time.  Our first boat had water in bilge by middle of season 
and I sponged out the bilge only to notoce the water was seeping in around one 
keel bolt.  I bought the appropirate sized sockets and tightened all the 
bolts while in the water and the leak stopped.  On haulout at end of season 
we notciced there was play in the keel and after that dropped and rebedded the 
On our next boat we accumulated water again.  this time 
it was from rainwater and leaks and around mast etc ... many many hours worth of 
rebedding everything and the boat is dry. 
Hopefully the 35-3 allows you to see the inside of the hull 
aft of that stringer so you can see where the water is coming

I've definitely ruled that out and yes, the stern section is bone 
dry.  Also water tanks were never filled and all thru hulls appear 
perfectly sealed.  This water accumulates after a day on the can, without 
running the engine or sailing.

Are you sure it’s not 
the prop shaft stuffing box that is leaking?  You said the stern section 
was dry which would indicate it’s not the stuffing box but just saying in 
case.   Sometimes a stuffing box will take time in the water to swell 
after long winter storage.

The previous 
owner says the bilge was dry the last season he had it in the water.  
I know him well and trust him that he doesn't recall a grouding either.  I 
know I haven't grounded it in the week I've had it in 
the water...  I'm wondering what happened in those 18 months on the 
hard to create leak of this size as soon as I launch when he saw nothing his 
last season with it?
