View Full Version : Ballast Pump Timer 2008 X15

06-30-2009, 12:27 AM
I'd like to thank everyone who provided information about the ballast bag upgrades. The information on this board is invaluable.

I've finished my install of fat sac ballast bags into my new 08 X-15 and have some questions about the ballast timers. I added the enzo surf sac port side, a 750lb starboard, and 2 250 lb XStar bags in the bow under the seats. These are all tied into the hard tanks using the overflow. Everything runs great except the timers.

I've tried programming the timers with no luck. The timers time out at 6 minutes which is fine for filling as i just turn off the power to the boat, wait 30 seconds and they fill for another 6. The problem i'm having is with the empty. No matter what I seem to do, once the pump gets to the first 6 mintues, i cannot reset the AI unit and have to flip both the startboard and port pumps off and on every 10 seconds to get them to empty.

I've read the posts on this board and get the feeling that if I upgrade the timers to the 20 minute modules, i will still have a problem when emptying. Is that true? If so, is my only real solution to bypass the AI unit with relays?

Here's some photos of my install. The only advice i can give is to: get a few extra spare part and don't glue anything until you have all your bags in place. The guys at fly high suggested glueing the screw in quick disconnects and i decided to do them in advance. Make sure everything fits, then glue them in.

The picture of the wave doesn't do it justice.

anybody have any advice on the ballast pump timers?

Is surfing the only reason you fill the ballast?

I would think the timers would be impossible to use if you fill the surf sack part way so that the weight is even when you wakeboard.

The timers seem like a PIA to me. Impellers are not that hard to change...if you have the pump in a place you can reach.

That wave looks awesome to me. Clean and long. We surfed a buddy's X-15 and only had 400 pounds in the rear locker, I thought it was pretty good with that alone.

Where did you relocate your batteries?

If i had to guess I would say this is on Lake Austin. I have the same problem with the timers in my xstar.

Hows the traffic on lake austin nowadays

You got it, Lake Austin. Traffic isn't too bad, there is usually a good spot to wakeboard if you don't mind the cold water up river. You can typically get in a good 5-10 minutes until a few tubers ruin the water.

Relocated the batteries to starboard side along with the charger. I prefer surfing regular so it was worth moving them to the other side.

If its not the tubers f'n the water its the surfers. JK ***I like the cold ars water coming from the Travis dam.

"if I upgrade the timers to the 20 minute modules, i will still have a problem when emptying. "

We installed the fly high kit in our 08 X-Star, which luckily had the right timers already.

Our experience is that, after reprogramming, the fill is flawless. Emptying, they may (or may not) switch off a couple of times. Interestingly, they do this when emptying the stock tanks.

We first empty the extra bags (AI never shut off) and then the stock tanks (AI sometimes shut off, but it is just a matter of restarting -- no timeout issues, as the empty cycle is not timed).
