Holes at least as big as original, or bigger would be better. One problem with the arrangement, the water drops from the holes straight into the bilge, a loong way from the stern access. Pretty much any solids that drop through with the water are going to be trapped in the hull. Give it time and that will be a lot of crud. Several owners have reported drainage problems, maybe related to inaccessible crud. Screens on the drains would be a good idea.

This is why the deck is stiff with mushy core. This is the piece of deck cut out for starter access in the engine bay by the previous installer. About 0.300" (5/16") laminate, then a 1/2" core of balsa. Wow. This is a 1971, pre OPEC oil embargo. Maybe later boats have less glass and resin?
