@Tausendburg Nice catch! It's really hard to tell, the water that Titan is standing in doesn't look all that deep. But there's also a part in the anime, haven't checked to see if it's in the manga, where a guy tries to leap onto one of the boats. We get a worm's-eye view of how far of a fall that would/could have been. So the Titan in the water could be large enough that it didn't hinder it any. Which leaves the question unanswered either way.

I don't think there are very many, if any outside of this image, of a Titan in water. My memory of the much earlier chapters is very hazy. But from my vague understanding of the geography, there isn't very many sources of water around the walled-in territory. From what I remember, a large source of humanity's water within the walls all come from inside Wall Sina, and is split into four sections to cascade into the other walled areas. That isn't to say there aren't large bodies of water outside the walls. But with how ineffective humans are against Titans, because they have a difficult time pushing the Titans back and gaining new territory, we'll have very few opportunties to see Titans near or in large bodies of water.

tl;dr: I don't know the answer to any of those questions.

My guess is that they're not so much afraid of water as they are inable to properly learn to swim through it. Remember, there's a part where the Titans try to learn to climb trees to reach the new recruits, but never quite figure it out. So I think it's more that learning new tasks is near impossible for them to do. Hopefully, Isayama will reveal more about what regular Titans can and can't do later on.
