Bullet Lines Complete Wakeboard Ballast Bag Kit, Portable Wake Enhancement for Wakeboard and Wakesurf Boats, Includes 2 x 550 LB Bags and 800 GPH Pump, Grow Your Surf Wake at 107 lbs per min (550)

Simple to use.... works great. Boat now has a pretty great wake. One all the way forward in the bow and one sideways in front of the engine compartment in the back.Well worth the money and would recommend.

We are 1st timers dealing with fat sacks and we found extremely easy and it was very quick just as advertised

I ordered these a few weeks before our yearly lake vacation. One arrived with a factory defect and Krypt Towers was very responsive and made sure I had a replacement before leaving on vacation. Great customer service goes a long way. I can’t wait to try these out next week!
