Ronix Eight.3 Telescope Bag 1100lb Fat Sac

A ballast system that finally makes sense. Fill and drain up to 3 times faster for a simpler, faster process when combined with the Ronix Eight.3 ballst pump. 

The  Eight.3 pump has a spring loaded quick-connect male adapter, that is designed to easily clamp onto the high velocity fill port of the Fat Sac. Ever had an unexpected flying water hose in your boat? Not no mo’. This 1 1/2” diameter fill port has a check valve water gate and a water tight rubber cap. Fitted for use with the high powered Eight.3 3000GPH or 3700GPH pump.

Eight.3 new port caps are all made with two sided vent slots which helps burp the Eight.3 system of all extra air while filling - more water equals more weight. Fill without taking off the cap completely and potentially losing it. These new 1” diameter port cap threads are twice as long, for a water tight fit.

In addition to draining the water here, you can also plumb this 1” diameter port into the Plug & Play of your boat.

Drop any size pump into the Ronix patented submersible ballast bag to drain the weight without having to attach any nozzles. The bigger the pump the quicker it drains without the inconvenience of air locking and re-priming. Because there is no priming involved with a nozzle you can now turn up the volume and use the industry’s fastest 3700 gallon per hour pump.

All Eight.3 telescoping chambers include an easy to open/close TiZip waterproof zipper.

This covers the telescope dry chamber until you are ready to empty your Eight.3 ballast system. It also acts as your alarm clock when you are filling to let you know you’re done. Not sure what we mean? Fill one up and you’ll see, it’s pretty entertaining.


  • By sourcing a new high strength vinyl material, Ronix now has the strongest ballast bag on the market. All seams and inserts are sonic welded to maintain the highest structural integrity. The telescoping drain port has a waterproof zipper similar to what is found on a dry suit.
  • There are three 1" Plug and Play ports on the new Eight.3 bags which will allow for system integration. One drain port on each end and one fill/vent port on the top of the bag. Riders looking to fill their bags three times faster will like the huge quick fill port on top right next to the telescoping drain hood.
  • Ronix has scrapped the traditional square or round shape for a new and improved trapezoid shape. This provides a base that stops the bag from wanting to roll when filling and draining. This feature alone will help boat owners that don't want to monitor their sacs more than they do their own children.
