I have found that there are six fairly small screws (#10 - 2 inch or so sheet metal screws) which are supposedly holding down the cover just aft of the pedestal on my 37.5. In addition to the six screws which hold the cover down, there are an additional six holes on my boat which were filled (poorly) with some kind of sealant. These extra holes were probably stripped out at some point before my time with this boat and they were redrilled about a quarter of an inch back from the originals. Some of the new holes which were supposed to hold the cover were stripped out, too and were only held in place with sealant. It appears that some of these holes are/were leaking and I am just posting my solution to this surprisingly poor design. I drilled out and countersunk and or ground out all of the holes oversize to remove all of the silicon or whatever sealant is there. Then I filled the deck holes (as well as the ones in the cover) with some fiberglass with thickened white colored epoxy mixed in to completely seal these holes. I discovered a few other mystery holes which also needed sealing in this process. This completely seals these holes which are obviously prone to leaking into the aft cabin. To retain the cover, I screwed a short piece of teak (epoxied 3/4 plywood would work too) to the underside front center edge of the cover. That wooden cleat must fit under the pedestal support bracket to hold down the front end of the cover. I am making a couple or maybe four fiberglass tangs at the rear inside part of the cover. Those will be drilled and tapped for a larger retaining screw. I am using 3/8 - 16 SS bolts for this purpose. No more leaks from the original screws. While I am at it, I will probably make some kind of larger drainage slots at the rear of the cover. Mine always gets filled up with a surprising amount of miscellaneous stuff which never clears the small hole that is there now. I am also making some kind of a fiberglass cover to deflect water and seal the wiring / shift cable hole. I haven't figured that one out completely yet but I know that there must be a better way than just gooping on more caulk. Hunter did so many things so well, this design surprises me. Any ideas on this cover?
