Marine grade plywood is just plywood that uses marine grade (waterproof) glue and has no voids in the laminate so that the strength is even and equal throughout the entire sheet. It can be of exotic woods, but is also available in fir and other common woods.
You can seal the wood with any good weather proofing sealant, like Thompsons.
It would be really good if you sealed the wood with a 2 part marine epoxy. That would make it really waterproof.
I would recommend using a piece of regular 3/4 plywood and after you have it all cut to size, covering it with a coat of marine epoxy, then another. It should last several years at least.
You can use regular ply because it is a pad for the motor and not the main structural member of the hull, so some minor voids are OK.
When you do the inside piece you may want to use something like Ipe, well oiled for a nice look and it has the strength to mount rod holders and things like that to it.
