1974 20' sceptre transom replacement and i/o to outboard bracket conversion

Here is the way I filled in the hole in the floor where the old I/o was located. This is the before and the after:



First off I took my fiber prep panel and waxed it well then primed it with a roller. Then I laid down several layers of matt. You can see it as it is still wet in the pic and then cured white in the next. Once that cured I cut wood blocks to fit the panel:




Then I mixed a thickend resin to glue the blocks down with. Note- I used the red hardener so I could see that the cabosil and resin had a even mixture of hardener in it. Once they were down, while still wet I mixed some resin even thicker to go between the blocks. Then once the blocks were filled I placed several layers of mat over it and got out any air. The vinyl ester with the red hardener turns almost a light pink.:

Once the core was dry I added my final layers of glass, a combination of 1708 and matt. Around the edges I added several layers of glass to make the edges one inch thick so I would have some meat to cut a vee in when I glass it in the boat. Here is the hole that it will be filled by this blank. It will be epoxied in place onto the stringers and then a vee ground on the edges and glassed to the original deck:

Friz,

Nice work - should be a sharp looking rig! Ever thought about putting hinges on that board and making a hatch out of it where the old engine box was? Seems like that might make a handy storage space under the deck?

It is fully glassed in now at this point but I made it beefy so that I can cut an access hole in the floor panel and it will be plenty strong even with a hatch cut into it. I more than likely will make a hatch for it, but not sure yet. I have a nice new abs plastic o-ring sealed factory made add on hatch that came with the master angler that was never used but think I rather make a custom fiberglass one.
