I have replced those fuse holders in the past, or at least one's similar. Any good Marine store that sells electrical parts should have them, or.... check Radio Shack. You will need to de-solder the old one and solder in the new one(s). Or, as mentioned above.... it may be easier to just repalce the whole panel. Rudy sells some good ones at D&R Marine, or again. any good Marine store that sells marine electrical supplies.
