The performance and durability you've grown to love from the Straight Line Sumo Series. The increased fill/drain times you never thought were possible. Introducing the Sumo Max Flow Ballast Bag and Pump Combo.

This is the complete ballast bag + pump combo. Included is everything you need for improving your wake for wakeboarding and wakesurfing. The total additional weight of 1,700 lbs. will have your wake looking bigger and better than ever before. The 475 lb bags fit great in the rear lockers of nearly any v-drive boat while the 750 lb bow bag can go underneath the bow seats for a clean, concealed look. The dimensions of the Sumo Max 475 ballast bag are: 45"L x 20"W x 13"H. The dimensions of the Sumo Max 750 bow bag are: 75"L x 56"W x 8"H.

When Straight Line brought the Sumo Max Flow Ballast Pump to market, it immediately took the reins as the fastest portable ballast pump at a whopping 4,250GPH. That massive flow fills over 200 pounds in 60 seconds.

We all enjoy our time out on the water riding, not waiting around on your ballast system to do its thing. Maximize your time out on the water with a Straight Line Sumo Max bag + pump combo.
