Have a 05 svfara 696 that I have got to put out a pretty decent wave by adding fat sacs. But seeing the new boats with the automated wake shapers and seeing a few aftermarket kits I decided to make my own. These allow you to run just stock ballast and can switch sides for surfing much quicker. I used 1/2" thick aluminum for the plates and just a pin in the sleave to remove them when not surfing. Can't wait to get out and give them a try.
