3. Drill a 9/64" pilot hole at each of the four key holes or marked locations.
4. For fiberglass with a gelcoat surface, you should overdrill the surface to
prevent the gelcoat from chipping when driving in the screw. Before drill-
ing the pilot hole, hand drill the marked location with an oversized bit and
countersink to approximately
3/8" diameter.
5. Drive the supplied #8 screws into the pilot holes. Screw them in about half
way.
6. Mount the module to the surface, slipping the screw heads through the four
key holes.
7. Press the module downward so the screws align with the narrow end of the
keyholes.
8. Tighten the screws. Do not overtighten.
