Im about to pull my hard tanks for 750 sacs in my rear lockers in my x1. Before i do i was curious if there was still an overflow option like the hard tanks have? in other words, when the bags are full do they spit the water back out like the hard tanks did, or will i have to watch them so the bag doesnt explode?

Just hook up the overflow hose that goes out the side into the sac, the hose should still be there when you pull the tanks.

Im a total rookie at this, i didnt even know that there was an overflow hose. Will it hook up to one of the air vent holes in the bag or just the main hole that the tsunami pump screws into?

you need to get the proper fittings for that from fly high or wakemakers.com from there, yes. it will hook straight in to the bags. the black hose that comes out the top of the tank is the vent hose (aka overflow)

Okay, it sounds like im set then. I got those in last week, thanks. Any idea if a non handyman is capable of pulling this off? I assume its just unscrewing the hard tanks and putting the bags in their place?

yes its a very easy job, unscrew tanks and place in sacks, are you connecting them to the factory ballast pumps?

Take care when installing the sacs. You want to address any sharp or abrasive areas that may damage the sacs over time, (screws, fiberglass edges, hose clamps) that sort of thing.

Yes just the factory pump. Do the bags drain well like the hard tanks do? Anything else that i should know before starting? do i need to beef up the locker divider between engine somehow?

nah itll be fine. youll have to get all the water out by picking up the bag and draining it over the side.

kalamalka - I am not certain when MC changed the ballast configuration on X1s 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 . 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 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

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.

Awesome. I'd like to see those as well.

I usually run the 1100lb bow triangle full up front when surfing and the rear sac on the surf side full. The box weight keeps the corner of the platform from dragging and making the wave wash over.

Here is th 1/2 inch poly board that I cut to match the divider. Put holes through it and countersunk the screws with sunken washers on the sac side and locking wing nuts on the other side all stainless steel. The second picture is with hard tank out and 750 sac empty. As on other poster said with a one way valve it will suck the sac dry. The last is with it full. There is the same clearance to the manifold as if it was empty.

Thanks for the pics. Do you have a pic of the surf wave too?

The first is me, I'm 6'4" so the wave is 2 1/2 to 3 feet, I ride from 2 to 8ft behind the boat. In the second picture you can see the length

Okay, I got the hard tanks out and the bags put in place. Do I just leave them like that, or do they need to be strapped down with something? Will them move around and pull the hoses out when full?

When they're full, they'll balloon out and there won't be any room left for them to move. ;)

Do you think poly-board is strong enough that you could just replace the dividers with poly-board? I had imagined reinforcement using steel brackets and beams, but if poly-board is strong enough, I'd consider using it.

I have only the polyboard and it maintains the normal distance with the 750 full. I was going to add a divider but but it holds fine.

mccobmd

Here is the engine compartment with the original divider in place, polyboard has been attached to it, 750lb sac full. No extra support other than the polyboard.

Now that ive got my 750s in and ready to go, what would you suggest for the rest of my bags for surfing? We surf 80% of the time on the starb side. I have two 400 bags and three 150 bricks. I dont have a ballast in the ski locker. Ive read that its good to put a bow sac under the seats upfront. Ive also read that 400 in the bow walkway is better with bricks on starb side bow seats. Do i need any more bags?

mccobmd
02-25-2013, 09:50 PM
with what you have I would put one of the 400's in the front bow with one fat brick in the bow, one of the 400's behind the driver with one end up on the seat, on fat brick in the starboard locker and one fat brick on the 400 up against the drivers seat. If you add a tube sac you can put it in the ski locker.
