I guess it kind of depends on what you are tying to do. If you want to cool the water, you are going to want to have the fans blowing over the water. So that would be in and out, or in and in. If you just want to blow the heat from the lights out of the hood, out and out might work. I don't really think that would work that great though.
My fans are also in line with my lights and are several inches off the water line. I have my fans blowing in and out because this blows air over the water, and clears the heated air out of my un open canopy. I tried in and in with my canopy open for awhile and it didn't make much of a difference.
