View Full Version : Is this the 2008 moomba gravity games stock ballast

Hoping that you guys could help me out. I was planning on upgrading the ballast due to everything i've read about the stock ballasts in this boat. I'm curious if this is the stock set up? http://imgur.com/a/4i01b

Cant get images to upload. Does anyone have pictures of what the stock pump system looks like ?

After doing some searching, I realized i confused Electronic valves for pumps which caused some confusion. I'm ordering the upgrade from wakemakers. Anyone pay to have it installed? what was the damage?

Yes that is very much the stock system. You will want to upgrade your bags as well if you still have some change left over. You will also end up changing all of your hoses to 1" along with all of the fittings. The guys at Wake Makers will help you with all of that.
Ask for the discount code, there is a thread for that. I wish I had known about that code at the time. I learned about it the day my box arrived :(

Looks like you have the original stock gravity III system. It used a single Rule 2000 pump to fill all the bags with the valves in your picture controlling what is on and what's not. It used 3 separate Rule 700 pumps to empty. Most people that switch over delete the valves and manifold and go with a single reversible pump for each bag.

Exactly. If you get a full Wake Makers kit, other than the current thru-hull, you are basically trashing 100% of the old system (unless you keep the bags). In addition you will be drilling two new holes in the hull to make a parallel system for fill and empty.

There was just a thread in the Supra forum on the same question:

I might be interested in your stock center bag if you are going to sell it. Let me know.
