I have a small (1/8") hole thru the hull of my ericson 28+. My manual says that the hulls are a laminate of fiberglass with a foam core. I have plugged the hole from the inside out, but am concerned that water may be getting in from outside and so between the layers of the fiberglass and foam core. Does anyone know if the foam core will absorb water and delaminate the area? I will be having hauled out and repaired right, but was hopeing to wait until the fall.

How did the hole get there 
I would NOT wait as no matter the core material water will work its way

I do not think your Ericson has a cored hull.

No Ericson I am aware of had a foam core. By all means, don't wait. Your hull is glass at the bottom and cored at and above the waterline and will quickly rot away when wet causing severe problems for you later, regardless of where the hole is. Water will almost certainly wick around inside the core to the wood.
There is only one way to fix this and it is from the outside.

You are correct, I re-read my mannual, in my panic I only saw that there is a foam core used, again, you are corrrrect, it is above the waterline, parts of the deck and cabin etc. I have put a 3/4 in screw coated with marine adhesive/caulk thru hole. Hopefully this will hold for now and slow down the wicking, I cannot get her out for a couple months. There is no wood within 8 - 12 inches of area, again, hopefully it will not have reached and saturated the area before I can get this fixed properly. Thank you for taking the time to reply.
