I used too long bolts to attach my foil with the foilmount. I need to fill the holes but I can't reach my finger in through the tracks,so it will be interesting. What should I use for filling? I've no idea what the board is made of but the previous owner did epoxy fiberglass patches on dings. Could I just fill them with superglue? Or would that be too brittle to last? Thanks.

If you mean you cranked long bolts into/through the foilmount, and the bottom skin of the board, you might as well try to fix with epoxy putty.
But.
Sounds very possible the board will self destruct over time from this, and possibly the foilmount too. I would use a leash around the mast to avoid loss of foil just in case.
And if you have a nice carbon foil, get a new board sooner maybe.

That's exactly what I did. I have some putty here, I'll give it a shot, Thanks.
P.S. I do have it leashed, this is just a temp solution while I figure out what size board I want.

I would carefully dripple some straight epoxy into the holes. Use a plastic spoon.

Thanks, but I already went with option number one. I stuffed an amazing amount of putty in there, I don't think that board is a normal polyester or epoxy board. Seems kind of soft. I have already damaged the foil and the foilmount to board connection looks fine, so maybe the board is tough enough.

If by over time you meant after about an hour of riding you were correct.
So now I have delamed the bottom of the board. I will take off foilmount and would like to just through bolt the foil on, since I now know where I want the foil.
Is there a way to reinforce the board somehow to make this possible? I thought I saw a post somewhere about doing this on a kiteboard but now I cannot find it.

First, you should remove all the delaminated area and all the damaged foam underneath it.
Then you should replace the damaged foam with new foam (except the area where the bolts will go, right around the foil's plate).
Then you can add high density foam or wood blocks to the areas the bolts will pass through.
Then you drill oversized (1/2"-3/4") holes through the board in the reinforced area for the bolts.
Then you fill these holes with epoxy thickened with a structural filler.
Then you relaminate the areas where you removed damaged glass, adding patches total 18oz+ of Fiberglass to the bottom and deck around the foil area (~12"x12" area or more).
Then you carefully drill the actual holes for the bolts through the reinforced areas you prepared. 1/16"
oversized so it will line up and work (because it won't be perfect).
Then you can add pads, paint, whatever, and drink a beer. Or throw it all in a bin if it didn't go right...

Awesome post. Now I can get to work.
I am going to order "structural filler", will west system 404 high density filler be good? It is supposed to be stronger but harder to sand, or can I get away with a low density filler like west system 407 with microbaloons?

You can make your own filler if like me you're cheap by using a pair of scissors and cutting up some fiberglass. Your board sounds pretty damaged. Friend of mine has that same setup, hope he's not gonna delaminate his board too.

The 407 is strong enough. 404 is basically talc, so the result almost like a quartz countertop (microrocks in plastic). Harder to sand and drill.
A good alternative is cotton fibers - cheap, strong, easy to shape. I forget the west product number for that.
Milled glass fibers work well too, strong.
Use slow hardeners.
Use isopropyl alcohol as solvent/cleanup.
No acetone.
Use gloves.
When you assemble the foil, use large fender washers under the screw heads on deck.
