[Bob Travis]

Thanks for the input!!  I think I'm going to try a stainless plug. I'll let you know how it goes.

The plug suggested by Dan is a good option but with either an electric or hydraulic controlled valve you could modify the inflow/outflow from the middle of the end-cap to the bottom of the tank.  I also wonder if instead of an FRP tank you could modify an AL-80 or AL-100 scuba tank to perform the same function.  Unfortunately they are not large volume and would not produce a lot of buoyancy.

I looked through the archives and can't find any discussion about water remaining in the tank. Is this a bad thing?  All the photos of all the other K-350's that I've looked at don't have any way of draining the last bit of water out of the tank. Can anyone give me some advise here?  I don't like the idea of water remaining in it long term.
