Thanks, guys.
Martin,
I didn't drill any bleeder holes in the core material, just applied the thickened epoxy with a notched trowel. The grooves left by the trowel allow air to escape as the parts squeeze together. The bond looks to be very good. I had to trim along the edges of the core, and I cut out the engine notch. All the bits I removed have a continuous line of epoxy a little less than 1/16" thick between the cores.
I got some resin squeeze out through the holes in the transom laminate when I applied vacuum there. The bond with the outer skin looks solid too. I tapped across the whole thing with the butt of my pocket knife and didn't find anything that sounds hollow.
I've laminated the inner transom skin, but didn't vac bag it. I'll post more pics tonight or tomorrow depending on what I get done today.
Dave
