Fat sac question x1, 205v, x2, xstar

[Memo]

kalamalka - I am not certain when MC changed the ballast configuration on X1’s from manifold to underwater thru-hull discharge. If your boat take-in and discharge water from the same underwater thru-hull and has 2 reversible ballast pumps fastened to the stern, here are some suggestions.
You can increase the ballast water flow by switching to 1” ID hose between the pump and the bag. Current factory hose is ¾”. After you have removed the tanks and the tank brackets, remove the two rear panels. It is good idea to check the pump impellers for condition and possible upgrade to green color impellers. While you have the rear panels removed, switch the ballast pump from right side up to upside down. You will see what I am talking about when you look at both stern ballast pumps at the same time. You need to switch only one of them. Mounting the pump upside down prevents water penetrating the electrical motor. This avoids future pump damage if the seal in-between the impeller and the motor fail. Current factory vent hoses that are attached to the hard tanks are not long enough for the bags. You need additional ¾” ID hose. Most definitely use the Flow-Rite Quick Release Connectors. You can purchase everything you need from Wakemakers.com.
Hope this helps. Good luck with your project.

Can you post pics when you are done?
My 06 X1 has sacks but they are the smaller ones. I would love to replace them with 750's.

I have 750s in the my boat. The 750s will put enough pressure on the dividers to push them into the manifolds. I added some stainless steel supports to keep the dividers from flexing after a season.

Memo had some good info in his post. I didn't use quick release connectors though. I just bought my threaded barbed connectors from lowes or home depot. I put some teflon tape on the threads and have not had any trouble with them leaking.

I had some trouble with the fill/drain hose from the pump to the bag kinking and reducing flow where it snakes around the rear panel. I put 2 90 degree elbows on it to take care of that.

The 750s are great for surfing, but you need a lot of weight up front to fill them for wakeboarding. I run the sac in the ski locker and the 1100lb bow triangle, and I still usually don't fill my 750s in the back all the way.

JR strengthening the dividers is a great idea. Did you screw the s/s supports to the panels or to the stringers? Flow-Right Quick Connectors allow easy removal of the bags to dry the carpet underneath. Also makes life easy while winterizing the ballast pumps.

I followed P hat's guide he posted on wakeboarder.com a while back. It has held up well.

I put the 750s in my 2006 X1, cut a piece of 1/2 inch poly board to replace the dividers. Ditto the weight up front. I never fill he back by more than half with locker full and 400 up front

[kalamalka]

Thanks all for the info. I assume that you fill the bag full on either surf side though. What bow weight do you use to surf with the 750 bag full? anybody have a pic of a divider that they made stronger?

kala, on my 205v, I surf with port locker 750# sac full, and nothing else (except all passengers sit on port side). My swim platform drags, though. I've tried weighting the bow, but it still drags. For my boat since my platform sits so low to begin with, it's best just to sink it so low that the water washes over it, and the wake is actually cleaner that way.

You may want to play with different configurations and see what works for your boat.

This is not necessary if you install one-way check valves on the overflow hoses. The bags will shrink like a raisin when they are emptied.

Your X-1 will want a lot of weight in the bow if you run (2) 750's in the rear.
Figure at least a sac in the ski locker and a 750 in the walkway.

I surf with the port 750 full and a 150 fat brick in that same compartment. 400 in the port rear corner, KGB full, 400 in bow down the middle with a 150 fat brick on the port bow seat. Good long wave. I have a tsunami pump and can go from empty to fully weighted in about 10min.

I have divider pics at home I'll post later tonight.
