[spareparts]

I use a 1 " hole saw. Moeller sells the flaring tool and the replacement tubes. I usally don't go back with the tube. I just remove the old tube, let it dry out real good, goop it up, covering all teh exposed wood with resin, epoxy, or 5200. After it drys, i use the garboard style that goes on the outside of the hull with the screw in plug
