The Sumo Max 675 goes in the bow of your boat for a cleaner, more balanced wake.


Adding bow weight is very important in both wakeboarding and wakesurfing. Not only does it help create a bigger wake, but also helps create the desired shape for best results. Compatible with SL's Max Flow Pump rated at 4,250GPH, filling/draining this bag will only take a matter of minutes.

    With the sumo max pump - perfect
    Adam Tabor

    I bought this with the sumo max pump. Fills in minutes and its plenty enough weight to let me easily dunk the bow underwater when crossing rollers.

    This bag really helps with surfing to lengthen the wave - and for wakeboarding to help the boat get on plane easier.

    Nice bag, poor drain port placement
    Noel Louthan

    Boat: 2006 Wakesetter VLX

    I mounted a reversible pump and got this bag to have a semi-automatic front ballast system. The bag itself is nice and if used with a Sumo Max Pro pump, it's probably great. The issue I have with the bag is the location of the drain ports. They aren't mounted low enough on the bag in order to drain out all of the water and because they're in the corners (as opposed to the middle), the hose connection gets smashed into the corners of the open bow.
