A great fit in the rear locker space of most boats. A popular option for building a better surf wake.


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.

The Sumo Max 650 ballast bag is a great fit in the rear locker of most v-drive boats. This bag + pump combo is a popular option for those looking to configure their boat for wakesurfing.

Straight Line introduced the Sumo Max Flow Ballast Pump earlier this year and it immediately took over the title belt for fastest portable ballast system on the market at a whopping 4,250GPH. A larger Max Flow Link Valve helps the pump get up to 50% faster fill and drain times than its predecessor, the Super Sumo Pump.

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 the all-new Straight Line Sumo Max Flow Ballast Pump.
