Radio Shack was a placeholder for the more complicated and technical explanation. In reality, replacing boat parts is done by manufacturers and marine shops that are usually located in or near marinas, much of the time requiring someone to order the parts special except for popular makers of products. There is no Radio Shack for marine electronics, but it'd be great if there were.
