I have a Centurion V-Drive Elite with a ballast under the middle of the boat, and borrowed a 400 pound Fat Sac from a friend to put in my back locker on either side for wakesurfing. The problem is...this Sac doesn't seem to be cutting it! With the Sac full, the water is still like 6in below the black bumper line around the boat. The boats I have wakesurfed behind, had the water line right at that bumper line. My wave seems too small, and all my riders including myself cannot find the sweet spot, and if we do, you can only hold it for like two seconds
So what should I do? Get a bigger Sac, or can another sac be put on top of the existing Sac and be stacked, or put another Sac in my back seat corner in addition to the one in the locker?
This is frustrating stuff...help!
