These are approaching 15 years old (2006 282 Sailfish) and I feel like it is time to replace them but only one I can easily find is a 50 AMP one from Blue Sea. Have searched and cannot find a 10 AMP or 4 AMP. Thoughts from guys on when to replace these. I could just take them out and clean them up. Nothing has screamed out to me that they are an issue so maybe I am looking for trouble even touching it. I just try to pick of a few preventative maintenance projects a year and thought this was a smart one considering what it services.
