SV211 tanks out bags in

[homer12]

This winter I’m taking out the factory hard ballast tanks and putting bags in instead. I’ve got 4 of the 3/4” fat sac quick connects for vent and fill hose connections. I need to get 1” connectors for the drain pumps. Everything else here is stock - pumps, hose sizes, plumbing, etc. I’m looking for suggestions on how people have done the factory drain pump when doing this? Leave under the bag, 90-deg or straight connector, placement? I want to do the starboard/cutting board support at the back of the bag like I’ve seen others do in here and mount the pump underneath. Any suggestions for fittings etc would be awesome. Boat is away right now but should have back in a couple weeks and wanted to order anything necessary.

Also, I can't find the thread anymore, but somewhere was a thread where someone made a cutting board support in the back of the storage compartment where the drain pump went under the factory hard tanks. I believe it was a 210 but same setup as my 211. I'd like to see those pics again but can't find the thread.

Check wakemakers for all of your fittings. You can email or call if you have questions. They have a complete 211 retrofit package which I used so they know what all is needed.

I used a cut up cutting board to mount the drain pumps. There are through hull bolts in the sump where the pump goes (it's been a while since I did it and I no longer have the boat, so I don't remember exactly what they are for) use those to secure the cutting board and attach the pumps to the cutting board using plastic pipe clamps from homedepot (there's a plastic conduit clamp that fits the pumps perfectly) If you use those bolts don't forget to properly reseal them. I used a short hose from the bag to the pump, then I placed a cutting board over the top of the sump so the bag wouldn't press against the pump when it's full.

Ok, I did t get to complete this project of removing tanks and putting in bags last winter, long story. Tackling it now. When I look at the drain and vent through-hull penetrations, they are below where the top of the ballast bag will be. Do I need to get some sort of valve, loop, or do something with the hose to keep water from draining when it’s full?

All you guys with the older SAN 210’s that have added 750’s, I’m sure I have almost the same set up with aerator pumps and plumbing. Have you had to add loops, valves, or anti-siphon devices to your vent and drain lines??
