I think this setup is create for the longer visual of the ship wake effect above the submarine bow after dive. This setup is in the val. files - like smoke. Do You use S3D, and what Uboat do you use now? If You use large numbers of mods, You should contact with moders they made this mods.
You see. If You know S3D a little You can chose the correct things from each mod and fit them to your game, to Your files, but if you don't know how do this...

Some mods fix these things, that others don't, and then we can't use all of them. Then we can fix it by the another mod, but then it will not work with some of the older mods, and we can fix the new one, and fix again, and again...

I only try to say:
If You know how to use S3D, problem is smaller.

So for example: If you using smoke mod at this time, You should install only the dat file with water streams, maybe some tga files also.
If in your old val. file - with smoke, ship wake setup is setting to 0,15, you can change it to 0,45. But if is more changes there, if more mods you using, then I can't help.

And also to me this is difficult to describe, because I never used the "Mod Enabling Tools". I always worked only on a files.
