The two that I have are way better than the ones you can buy at BP or Cabelas. Here is a link: Livewell Timer They are a little pricey but you can set the on/off times to what ever you want and it monitors your batteries charge and will shut itself off if the battery starts to run low. It is also solid state and waterproof. I did a lot of research on these over the winter to make sure I installed good ones. Hope that helps. I just installed 2 in a old bass tracker II that I modified this winter.
