Does gravity effect the density of water on an ocean planet?
I'm designing an ocean planet. I did a quick search with this question on the interwebs, but nothing that came up was helpful (I don't have any physics or scientific background). I was wondering whether on an ocean planet, with a gravity of about three-fourths that of earth, with a radius comparable to earth, if the water would be any different (less dense, etc)?
Thanks!

Water is, generally speaking, incompressible. It doesn't act like other liquids, at least not until you treat is as though it's already at absurd compression as it is. I highly doubt that water would be functionally different.
Additionally, a fun fact pertaining to water: If it floats, it will float regardless of gravity. Gravity is a significant part of the equation for flotation, so barring other issues, if something floats on Earth, it'll float on a world with half gravity, or even double gravity. Of course, that's not all there is too it - A ship that's structurally sound in half gravity may not be structurally sound in double gravity, etc
