Gravity III Balast system darining
Hi All,
I have an 04 Mobius, when I am done surfing or wake boarding at the end of the day I am unable to completely drain my bow bag as well as my ski locker bag. This is leaving quite a bit of extra weight in the boat for hauling down the road. Any tips to get all of this water out of the bags?

the Gravity III is notorious for this, just not the greatest of systems. Like Stazi said, check valves will help. From there you can upgrade the entire system to reversible pumps. It's pricey but a great system.

You probably have the 3/4” hose so this is the best price I have found.

Check valves won't help with the g3 ballast that's an aerator system. You can add a second drain line to the other leg of the bow bag, that will help but you'll never get the bag completely flat without upgrading to reversible pumps and check valves.

Turn off the pump when the water stops flowing, raise the wake plate, drive forward with the bow elevated and start the pump again will get most of the water out.

Not sure if the system is the same as my 2011 and it took me a while to realize this. After bags were down to zero, you can flip the switch off and then back to drain again and it will run for another 30seconds. Do this a few times while raising the bag and your done.
