So I taped the gel coat and ran the hole saw backwards until it penetrated the gel coat by a few mm. It didn’t take long. From there I ran the saw forward, and the hole came out very clean with no chipping. I did the same thing for the screw mounting holes (drilled backwards through the gel coat), resulting in no chipping and very clean holes. All is mounted in the flat surface adjacent to the shore power to avoid any compromising of the backstay and issues from a curved surface. Gland went on smoothly, some soap got the cables through the rubber gasket smoothly (I didn’t cut it with a razor per Seaview’s instructions), and I’m very happy with the result.
