I upgraded my 2007 Supra 22SSV this year with Johnson Pumps for each ballast bag.
I have three Solenoid Ballast Valves and Manifold System for sale.
I just purchased one of these new from the local Supra Dealer last summer - $24.43 + tax
Rubber Gasket in the Valves
On/Off plastic switches working not broken
Plastic Water Strainer

Used. Good Shape. Working - when I removed from my boat this year.

New they are around $25 each.
If interested, make me an offer.
