Yep, thats the welds I am talking about, but When I pulled my snails off I saw what looked like a crack running from the water passage to the stud hole so I figured it was a repair. Not so sure now.
CP has these. They were listed in the '04 catalog as H.M. and sold in pairs. They now say they're out of stock.

Are you running your outlets OT or thru-hull? If thru-hull do you have flappers? Without flappers you could still be getting water pushing its way past the riser.
