Integrating Fatsac 750lb Bags Into 2004 SAN210TE

[Nzblacky]

Great thanks core-rider. Do the fat sacs drain via suction back through the overflow line to the hard tanks?

[core-rider]

Yes, but I do have to keep an eye on them sometimes. They can cause a vacuum on the hard tanks when empty making the hard tank collapse into itself. I tried the 1/4" tubing from the fill to air-bleed hoses, but that didn't seem to help much. Hopefully this season I will be running 750s without hard tanks and it won't matter anymore.

Has anyone here personally experienced a failure with this setup?

[faralta]

I learned about this while shopping for my boat a few years ago and came across a few boats with broken ballast gauges due to this. I have not personally experienced it because I avoided it from the get-go.

[SCNautique210SAN]

Gotcha, thanks. So faralta, I noticed you only have one pump in your diagram. Is this the setup in the 06s or did you remove it and re wire? My 04 doesn't have a single reversible pump it has a fill pump and a drain pump that's located below the hard tank in the rear.

SCNautique210SAN, I have three reversible pumps (Jabsco Water Puppies), one for starboard tank, one port and one for the belly tank. They are stock with my year SANTE and CC probably went to this change-over shortly after your 04. I can operate each pump in either fill or empty mode.

[SCNautique210SAN]

Hmm. I have a total of 6 pumps (3 1200 gpm tsunamis and then 3 1100 gpm rule tournament series to drain). I have the same keypad as you I think just wired differently.

Mine drain through the side of the hull next to the vent, but out of curiosity do the 06's have this as well? Or do they somehow drain back through the intake?

[faralta]

yes, they drain back through the intake via the reversible pump.

Sorry, looks like this works for pics. I tried a pdf of my diagram, but jpeg seems to work better. Anyway, this is the manifold and my plumbing diagram:

where can i buy that manifold ?

I'll try and get some pics of my install this weekend... hopefully, if I can get through the snow to the barn. Think spring.

[SCNautique210SAN]

yes, they drain back through the intake via the reversible pump.

Bummer, then this setup won't work with an 04 setup like mine.

[faralta]

too much snow, too cold (-17F), will try again later for pics...

Well, It could still work, you will just need reversible pumps. The drain holes near the vent would not be used, but it would still work. If you want to use the drain holes for a visual confirmation of draining, you could still do that too, just would need some one way valves installed.

I think i would have to replace the pme box? Or do the reversible pumps have two positive and two negative leads.

Finally got some pics of the soft bag (on top of hard tank) and the manifold I installed:
