You should be looking at least twice the input side. So if your using 20mm going in you want a good 40mm with no restrictions going out.

Hope this helps.

Agreed, at least twice.

You need to allow for movement on the boat, rocking and swaying and different trim levels when you are on and off the plane. All of that water is not going to find the right spot at the right time. You need to give it some options

I have a 19mm inlet (500gph) and a 30mm overflow in each corner at the top.

I also have a bung at the lowest point to drop the water at the end of the day.
