Item: S10471

The 650 pound version of the Sumo Max series with Sumo Max pump compatibility.

A great fit in the rear locker of many v-drive boats, this is a perfect option to weight your boat for wakesurfing and wakeboarding.

Perfect rear locker bag for 2003 Moomba Mobius LSV

I bought two of these and the Sumo Max pump for my 2003 Moomba Mobius LSV. Perfect fit, didn't need the bracing bars, was able to store a neoprene life jacket on top when full. The burp valves make me wish my stock ski locker ballast had one. I used this with the stock ski locker bag (exceeding the recommended weight limit, but it handled and floated fine with large waves coming off other boats), it put out a huge wakeboard wake & surf wave (using a suction cup wakesurf device on the side). The swim platform sat about 5 inches under the water, and the stock ski prop barely pushed it. I had to use the wakeplate to accelerate past 12mph, and then I could adjust the wakeplate where-ever I wanted & maintain speed on plane. To improve speed control and accelerating with weight, I upgraded props to a 14.5"x14" ACME 1235. Now looking at a sumo sack for the bow for wakeboarding and/or making a longer wakesurf wave with less reliance on the trim (though these 2 bags alone will do the trick for surfing)

Recommend as a rear locker bag, not as a floor or seat bag.

This bag would be better suited as a rear locker bag on a older boat with a smaller rear locker. When full its a little too tall and has a tendency to want to roll over if filled in the middle of the boat. I should have bought the 475 size for my needs.
