This is the perfect sac to keep in your boat for those days when you need a massive weight. It fits fantastic in a few places - rear ski locker on a direct drive, walkway to bow on a open bow walkthrough, or a side of a DD for surfing. I regularly use it in the front center to keep the nose down for surfing. As always the Fat Sac's quality is unmatched.
Ian, the Fat Sacs and Tsunami pump are pretty awesome and I give them a 4 star rating. I would give them a 5 but the quick connect valves sometimes dont jive right with the tsunami pump connection and therefore fall off sometimes during filling or emptying. Overall I am happy with the purchase and would definetly recommend to others. I have a 2011 Malibu 247 WakeSetter. Without the additional Fat Sacs it was a challenge to perfect the wave for wakesurfing. When we added the Fat Sacs it brought a whole new life to the wake and simplified dialing in the perfect wave. It was a night/day difference! I did end up reinforcing the engine compartment side walls in the back storage lockers to prevent the Fat Sacs from breaking or caving in that plastic side wall. Works like a charm I would recommend to others to maybe consider an additional Tsunami pump if you are filling additional side seating and front sacs like I bought as well. It is a huge time saver if you have 1 or 2 additional pumps for others to work on with you at the same time.
The central bag in my X10 needed to be replaced and the Pro X Series Tube Sac was the best fit. And no need for a second protective layer, this one has a "tough skin". Combined with its 2 Pro X Series V drives sacs, my X10 is now fully converted!Yves
This sac works great as added weight in the bow. I use this sac in the walk through on a 1993 ProStar 205 in combination with a rear 750lbs. Works great and the perfect size.
