I was installing my transducer yesterday, and noticed water weeping out of the holes. I started drilling small holes in the bottom near the back, and got more water out. I've read old posts about injecting epoxy into the holes. What I was wondering was how you inject it into holes in the bottom of a boat. I had a hard enough time trying to get it into holes where I could just pour it and let gravity take over.
Any help would be appreciated.

Use puttty epoxy. Available at any hardware store.

I use horse syringes - various sizes, relatively cheap and available at farm/ranch implement stores. ----- Jerry/Idaho

West System (found in West Marine catalog, and other places) sells plastic syringes made just for injecting epoxy for about $0.10 apiece, it seems like (maybe a little bit more). You cut the tapered tip off to get whatever diameter you want and throw it away when you are done. I usually clean them with acetone and get two or three uses out of them, being the cheapo that I am.

Gep, Take a piece of duck tape to cover holes overlapping an inch or so, find and mark holes with marker, have second piece of tape on hand, then take west syringe with tip cut at sharp angle and inject through tape till hole fills, not too much. You will see tape bulge. Then cover with tape as you withdraw syringe.
Before you start,
I've done this method more than I care to remember and it works well.

Thanks for the info guys, I think I have bigger problems though. In my infinite wisdom (I'm an idiot), after I drilled the holes I thought I would just take my compressor and blow some air in there to force the water out the other holes. Well it was working fine until I heard this rumbling sound, turns out I was delaminating the hull from the foam by doing this. I now have two sections where it delaminated the hull about 6" x 16". You can't tell by looking at it but I watched it happen so I know it's delaminated. I then decided to switch to a vacuum, I duct taped a clear 35mm film cannister onto the end of my wet/vac hose to see if I would get any more water out. I got a little more out. Now what do I do?

Off the top of my head, I would suggest in the delaminated area you will drill an array of small holes, inject some epoxy into them, and thus rebond the foam to the laminate skin.
There may be other solutions, as I am sure follow up postings may reveal.
