I have had the same issue in the past. If you are working with fiberglass you will need to remove the liquid nails and and clean the hole with acetone. Make sure there is no liquid nails remaining in the hole. You need to drill the hole larger but if you do, start the drill in reverse to start. That will widen the hole without shattering the gel cote. Then drill the hole as normal making it a little larger than the original hole.
To repair you should use epoxy mixed with fiberglass mat. Any auto parts place should have both. Cut the fiberglass mat into small pieces and mix with the epoxy. Put the mixture in the hole making sure to force all of the air out. Let dry and then drill a pilot hole for the screw.
