2004 gs 170 takes on water

the scupper seams to be below the water line and will take some water onto the hull is this by design ? Is there a remedy? Also I wanted to order dash pano controls any suggestions?

    My stern deck drains are also below the waterline.

    It's always good to run water through your deck drains to make sure there is no debris (which often there is) in the line.  This way you can make sure nothing is holding the scupper plate/valve open all the time.  It's most effective when the boat is out of the water. 

    Having said this, scupper plates/valves rarely 100% completely seal the drain from incoming water, so seeing some water in the drain or hose is not uncommon as long as it is not pouring in.

    If you are talking about the switches on your dash panel and they are of a rotary design, then they should be made by Sierra Marine,

    Here's a link to the rotary switch page of their on-line catalog so you can see if they are a match:
