inside or outside

What is Luan ? I will be re-doing the transom in my Tsunami as soon as I can pull/sell the (2) i/o's I have in there now. I'll also be removing present engine stringers and installing new ones for a single i/o. Has anyone done this job that you know of ?

I will be going from the inside and was planning on using (2) 3/4" pcs of plywood and polystyrene resin as replacement.

As for tools to get the old core out ? I can get my hands on a compressor - if I was to buy a tool for the compressor to remove the core, what would it be ?
