I am looking for a 12 volt electric 3 way ball valve to switch the exhaust water dumps from through the transom to fill a ballast tank? Anyone know of where I can find these? Thanks, Dave

Try Grainger.com, or McMaster-Carr. Deltrol makes some electronic dump valves, but none of the ones we used were 3-way.

Yes contact Mark @561-282-8220 with Tsunami marine, he has a three way valve that is all stainless and looks awsome. It was intended for freshwter flushing system but can help your needs as well.
