Uhhhmmm, what kind of holes? Where are they located? What kind of boat? Pics would really help us to help you. Bathtub caulk is never a good product to use to fix a boat. Fiberglass resin is preferred.:D

What are these holes? Were these "Man Made"?

ya they were the original holes for the old motor that was on the boat but we replaced it and now when we put the new motor on the boat and the old motor had a different mounting bracket so now we are going to have to drill new holes and fill the old ones

So these holes are on the Transom? If you could back off a bit with the camera and give us a better overall perspective it would be a big help. If they are indeed on the transom then I'd recommend using some Bondo Hair to fill them. You can then either gelcoat or paint over them.
