I"ve searched this forum and briefly online to find the right time to replace both the internal and external Anodes on the outboards. A lot of answers seem to be when they show signs of corrosion. I would think the answer would be when you see actual degradation or size reduction from your anodes because its doing its job. Is it true that if its whiteish and has corrosion on the external surface area of it that it needs to be replaced? I would think there is a lot more zinc there, or is it because if its not on the surface area it loses its active factor. I would assume your actually OK until the Anode is actually eaten way, but perhaps I"m wrong and I need to replace.
My Internal Anodes on my Yamahas look like very similar to the ones in this video at the 2 minute mark.

My exterior Anodes do show signs of wear but look as if they have a lot of life left.
