Jesse,

Here’s a combination 1-1/2” thru hull and matching seacock kit from Defender Marine ( www.Defender.com<http://www.Defender.com> ).  Marelon is a glass fiber reinforced polymer composite that was developed for structural marine (i.e. seawater) applications.  Marelon is not susceptible to electrolysis corrosion the way bronze is.  Basically, you would remove your existing thru hull and replace it with this.  The kit includes straight and 90 deg hose barbs for attaching the drain hose from the galley sink.  I would use the straight hose barb to avoid the potential flow obstruction in the 90 deg elbow.

Dave, where did you get the thru-hull valve?  Can you tell us about the installation process?

Thanks,
