Product Info

Want an alternative to cramming the back of your boat with 400 lb heavy weight linebackers every time you want to enhance your wake? Upgrade your set up with the Eight.3 Telescope CTN 400 lbs V-Drive Set Ballast Bag and fine-tune that perfect wake. A high speed pump port and telescoping dry chamber ensure the fastest fill rate while high strength vinyl construction makes this bag super strong. A new Ronix/ Eight.3 designed trapezoidal shape ensures that this bag won't slide around behind your boat so you can spend more time in the water and less time focusing on your bag. Trust us - once you give the Eight.3 Plug n' Play CTN 800 lbs Ballast Bag a try, you won't ever go back to using football players again.

Product Details


ConstructionBy sourcing a new high strength vinyl material, Ronix/Eight.3 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.

Constructed from a single layer of the same durable yet flexible material used to build white water rafts and Fly High Pro X series bags, the Ronix ballast bags offer unmatched strength and durability.


Weight800 lbs


50" L x 22" W x 20" H


All Ronix/Eight.3 ballast bags feature multiple sonic welded threaded ports built into the bags during construction.

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.

Recommended Bag Placement

Designed to fit in the rear compartments of any V-drive boat

A pair of Ronix/Eight.3 V-Drive Sacs also works great on either side of the engine in a direct drive boat for a great wakeboard wake. You may put one on the side of the engine and one between the engine and rear seat for a perfectly surfable wave.

Additional Features

Anti-Roll Bag TechnologyTapered design with the widest area of the bag at the bottom creating a trapezoidal shape: Long gone are the days where your bag flops around in the boat.

Telescoping Dry ChamberAll Eight.3 Telescope bags feature a telescoping dry chamber with a waterproof zipper. Once this chamber is opened, you can drop any size pump into Ronix's 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.

Comments about Eight.3 Telescope CTN 800 lbs Ballast Bag:

We have two of the telescoping 800 lb bags in addition to two of the regular eight.3 800 lb bags for wake surfing. The regular bags are piped up to the stock boat ballast system. We can fill and drain the telescoping bags with the 3700 gph telescoping pump quicker than the boat system fills and drains the regular eight.3 800 lb bags. The telescoping bags with submersible pump works pretty good overall. The quick connect system for filling comes off easily which sometimes means you accidentally get some water in the boat. The connection could be better.
