Got back to work over the past few weekends, still waiting for some warmer weather to get more fiberglass work going
Dilligaf - Yes, the epoxy/cabosil was used as an adhesive.

laid down two layers of 1708 against the inside of the existing transom skin.
Mixed up a thick cabosil/epoxy paste and troweled it onto the 1708, made a bed of the paste for coosa transom to set into, them clamped everything together with 2 x 4's
As per some previous discussions, it was not fun removing the carriage bolts, till I got out my new favorite tool, the hand sledge!

I put the transom cap mold on just to get a feel for how the transom will look
laid up two layers of 1708, 6 inch 1708 tape along the edges and woven roven on the inside. I could use some thoughts regarding if this will be strong enough to support a full bracket with a 425# motor? should I grind it up a bit and add more layers?
