What you say adjustments, do you mean like a wakeplate?... if so a photo will help.... even with a wakeplate adding ballast will be the biggest help.
...just so I'm clear, we're both talking about this boat (give or take)
If so, I'm a little hesitant to believe its got a "hell of a wake" .... it was 100% designed to not have a "hell of a wake", literately designers tried to make this boat make as small a wake as possible..... if I'm wrong, kudos and enjoy!
