yes Gene. I just found a spot in the center of the bilge(boat's centerline) and drilled straight down through the fiberglass. When all of a sudden lead shavings came out the drill bit I knew I was into the lead. In my boat the lead wasn't more than a few inches under the fiberglass. I used about a 5 or six inch bolt. If you know your lead is deeper down, just use a longer bolt.
