Sun Fish auto bailer

I have a minifish which apparently uses the same auto bailer as the sunfish; it is leaking a cup or two of water per outing; I have it unthreaded and have been told to use silcone sealant; I am assuming around the gaskets? not the threads? any ideas; if this doesn't work out I can get a new part for about $60, thanks

You could use a silicone caulk for this.
I wouldn't. Silicone can be messy to work with and if you have to take the self bailing scupper out again you will have to fight the silicone to do so.
I'd recommend Butyl tape for this application. Easy to use, easy to clean up. In fact I'd use Butyl tape for all through deck penetrations on a Sunfish/Minifish hull.
You can find it at most RV stores or Need Butyl Tape ?? Photo Gallery by Compass Marine at pbase.com

I think he means inside the hull, not the cockpit

The problem with the Minifish, it is the lowest part of the hull (aside from the CB) so anytime you run it up on a beach or lay it on the lawn, it takes a lot of abuse

I was trying to say that it sounds like his autodrainer is leaking where it meets the hull and letting water inside the hull, not into the cockpit.

It will need to be removed and rebedded

Do you have any photos of the existing sealant? If it was already silicone, it will be hard to get anything else to stick nicely, and probably not worth the effort to change. In that case I'd use Lifecaulk(a blend of silicone and polyurethane and rated for below waterline usage).
If it wasn't bedded with silicone before, I'd use 4000uv. I would use a thin layer of the sealant on both sides of the gasket(if it doesn't come with any guidelines saying no, since some gaskets don't work well with sealant), and also portion of the threaded portion that would be penetrating the hull.
