Power Outage

might try cleaning all of your battery connections. My boat did the same thing earlier in the year. I cleaned all the connections at the battery and all has worked great since. They were pretty corroded at the time.

Those breakers can sometimes “look” good, but may not be. I carry 2-3 extras for the different size breakers that are in my CougarFTD. Ive had to replace just one on my 09. On my 06 I had to replace two in the two years I had it. On my Baycat, I had to replace them several times, but that was no doubt due to my trying to use that boat in salt water…it just was too much corrosion.
