Its been awhile, and progress has been a bit slow.
First thanks for all the ideas on the placement of the transducer on my boat. Some very interesting and innovative ideas that have me thinking on how I will want to mont my ducer. For now I think I will fill the 3 existing holes in and start fresh with a new one.
My materials finely arrived so I could start laminating the new core into the boat. I decided to use epoxy resin from US Composites for the build.
For the transom
I really wanted to enclose the transom, and put on a Hermco outboard bracket,but unforchantly that will not be in my budget at this current time, so I decided to leave it open.

After I made a template out of masonite board I cut two pieces of 3/4in marine ply, and bonded them together using a think-end epoxy putty, that was clamped together using drywall screws and wights.

To clamp the new core into the hull I decided to use 2x4 with carriage bolts, and drywall screws, to sandwich it together. I also decided to take the advice of a fellow form member and raise the transom from 25in to 30in.

Bolting the transom together was a bit of a struggle doing it by myself, especially getting the carriage bolts lined up level, but it worked out ok in the end.
The next day I decided to prepare for the 1708 cloth by making some fillets around the perimeter, of the newly installed core.

Next came 3 layers of biaxial tape over the fillets.

I was not completely happy with the uneven suffice of the top on the new core. I wanted to make it level before I layed up the 1708 cloth. So I decided to make up a batch of thicken epoxy to make the surface even, before the cloth layup.

thats all for now
