I'm kind of figuring it out as I go along. I'm thinking that maybe I should've just cut it all out with a chainsaw and poured it. It feels strong so far but we'll see. It would suck if once I'm done glassing it and gelcoating to have it be weak. 
I built up the area between the cap and top of the transom with 1708. I'm going to grind the whole seam down and glass it together. Then I'll put the engine on and run it. Its been tough budgeting my time between my Wellcraft and Grady.
