I apologize....I just saw this message. Did I ever get back to you on this? The custom swim deck made a huge difference in cleaning up the wake. The old "stock" platform would dig into the wake and destroy the lip. The stock deck is to wide and has a lip on the underside across the back. If you see a lot of white wash along the crest of the wake "no clean lip" then the platform is the culprit. Hope this helps. Sorry it took so long. Let me know if there is anything else I can suggest. Good luck.
V-man question about your custom swim deck. What change did it make on the wake after adding in the custom deck? Did you surf the old deck with the weight you have now? I just got a 2008 x45 about a month ago and I am just trying to dial in the wake. Thanks for your time,
