I have a 2005 Supra 21V with stock ballast (600 pounds center locker and 400 pounds each side). Does anyone else have the same model and around the same year boat? What have you all done to get the right wake? We surfed for the first time tonight and just couldn't get the wake dialed in right. Thanks!
Fill the centre ballast and surf side locker ballast to the max! 400#'s in the locker will not be enough. A 750# sac is better. Get all the passengers on the surf side towards the back, trim tab all the way up and go 10.5-11 mph.
I'm a SC fan, so don't take this as a bash, but you have an awesome wakeboard boat, not a great surf boat. The hull design makes that boat tough to get a great wave. Try the setup suggested and post some pics.
