This complete ballast bag + pump combo will instantly create the results you are looking for. Adding 2,200 lbs. of additional weight to your boat will help create a more sizeable wake for both surfing and wakeboarding. The 800 lb. bags are designed to fit in the rear lockers of a v-drive boat while the bow bag goes up front to create a balanced wake. The included 3700GPH Telescope pump makes for quick fill/drain times while out on the water (less time waiting around and more time riding). This bag + pump combo has everything you need to get out on the boat and build a better wake.
