Right now, I understand that the southern hemisphere has more water than the northern hemisphere.

Climate Science Investigations South Florida - Temperature Over Time.

I'm curious to know for many years this has been the case.

There were probably many times in the distant past this was true, many models of continental drift indicate 600-400 million years ago this was the case, with one of the main continents over the South Pole and not as much land in the north.

I would guess that the last time there was more water in the Northern Hemisphere than in the south was about 300 million years ago, prior to the formation of Pangea. The supercontinent of Gondwanaland (modern day South America, Africa, Australia, India, and Antarctica) was entirely south of the equator, and only parts of North America, Europe, and Asia were north of the equator. Further back, 500 million years ago, almost all of Earth's landmasses were in the Southern Hemisphere, with the possible exception of North America and Australia.
