I have a 2001Ski nautique anniversary edition that has I believe has an origami tower also..at least it looks that way. The dash control panel looks like the same as it would for a nautique air so it has a ballast fill and empty button but of course it does work as there is no system. I was wondering if I could install an aftermarket system?
+1 for wakemarkers .... they'll be able to help you out big time.
Not sure if having rear ballast on a switch is much better then throwing a pump over the side though with a direct drive. I would assume you want to pick/move the bags when not full... so having it plumbed it might not be the best option.
The bow on the other hand (assuming you have a closed bow) would be nice to have plumbed in since it would rarely be moved.
so do you have rear storage? if so, I would plumb in ballast and leave bags tucked away in rear storage. pull them out and use some quick connects to hook up your hose. could be really clean if done right.
