Probably not Marine Ply for this application.
Proper marine ply is certified to a certain BS - this guarantees various
things such as the absence of voids (gaps within - not between - the layers)
etc. It's horrendously expensive, something knocking on Ł100 per 8x4
sheet. It's used for specific tasks where these things are important, but
of course this doesn't stop home & garden improvement programs specifying
"marine ply" for all manner of jobs.
I think for this application you're probably looking for exterior grade ply,
or WBP (water & boil proof). Some far-eastern hardwood WBP ply can also be
horrendously expensive - you don't need that grade of stuff either.

On the home/garden makeover programs you can often see the ply
de-laminating in the first light shower of rain :)

I've noticed that a lot of the sheds seems to only sell WBP ply anyway
