View Full Version : I have the answer! 2.0

I finally got out this last weekend and tried out the ballast upgrades.
With the dual pump configuration and the ballast springs removed I went from filling about 25 minutes fill time to 17 minutes fill time with the 1200lb enzo sac, 400 lb center sac, and about 250 in my bow sac.
I do know I want to upgrade to a integrated ballast bag.
For some reason both of my front sacs were full of air and took longer to fill initially. I'm pretty happy with the results.

That is great to hear. I guess i will take that spring out and call it good. Also happy to hear you made it out on such a nice weekend.

The day after I pulled the springs in my 08 Outback V, the center bag filled freely. The next weekend, it was under control. This weekend will be the tie breaker, but my setup may not be spring removal friendly.

where can i find the thread on the ballast upgrades and removing the spring?
who was the originator of the post?

I think it was Moombadaze. I know Newty was in there too.

Help me out if I'm missing something.

Newty, thanks for posting up all your mods, your boat is looking nice. I checked out all your ballast upgrade info and was curious how the pressure worked for filling your integrated bow sac. Correct me if Iím wrong, when your center sac gets full the pressure sends the water to the front sac instead of emptying out of the boat like usual. Did you do anything to keep the water from diverting out to the empty lines or do they just flow to the front sac with no added valves?

All I did was run a hose from the normally plugged vent on the floor sack, and run that to the bow sack. Because the bow sack is at a lower elevation than the drain for the floor sac the water takes the path of less resistance which it to the bow sack. The bow sack has its own overflow. and when it is full water comes out of both through hulls. It does overflow a little out of the floor sac when the bow sac gets fairly full.
Make sense? I hope so cause it doesn't make sense to me.

10.4 makes perfect sense. Thanks.

I replaced my rear sacks with the 750's last year and wanted to try and hook up my two old smallers sacs in the bow. We will see if I can come up with something.

We've had quite a few questions about this lately, so we through together a little article on the factory Moomba Ballast System (http://media.wakemakers.com/2009/05/pre-09-moomba-factory-ballast-system-upgrade-information/) that may offer some additional info on how you can decrease the fill times.

Great idea Ed, I'll work on something about the new boats.

I'll also get images up the next time we have a Moomba come through; I agree, they'll add a lot to the description.

Did you run the boat without the ballast bags full? On my system removing the springs allowed the bags to fill while underway without the pump on. The water would also free flow from the high bag (1150 bow sac) to rear bags. (My rear bags are 750lbs so I don't completely fill them unless we are surfing. I need to control the rear bags independently for side to side weighting in order to keep the wakeboard wake clean)

When I would fill port or starboard bag to surf the water would bleed to the unfilled bag which kept the boat from listing for the nice surf wake:cry:
