Rowmark has some really neat engravable acrylic sheets. You can get solid colors, simulated wood (not sure if it's suitable for outdoor use though) or even simulated granite.

Using this would allow you to have the switch functions and the big SeaCraft logo engraved on the panel.
I've used this stuff before and it yields very nice results.
Good luck.
