So your question is that your Ttop basically is loose or ripped out from deck??!!!!!!!
Look for some stainless toggle bolts. I know they make toggle inserts for helm pedistals...might work to hold down t top securly as well. Or go with above option of epoxy...also might try cutting foam material a little wider and deeper than holes (like a cylinder shape), soak with epoxy..push foam material into holes until top half of epoxy soaked foam material is sticking above deck. After epoxy dries grind down dried epoxy/foam material and redrill for fasteners. The dried epoxy foam material will extend down past underside of deck and give your bolt more depth to screw into.
