I'm pretty sure neither you or anybody else made that statement on the other forum. But since you've made it here and it's about as clear as mud, maybe you can enlighten me as to why electrical current would find it "so much easier to go to the zinc on the prop" as opposed to the shaft.

Jeezus, not arguing. Just do not understand your logic. Was hoping you could explain it. I guess that's asking too much.

BTW- you presume that I know who you are on the other forum. I do not.

Is the prop zinc more active, or its position unique that causes it go faster than the zincs on the prop? My goal was to have the prop zinc last all season so I didn't need to have a diver replace it mid-season.

Thanks for any insights.
I suspect the primary reason is that the whatver metal the zinc on the end of the Maxprop is protecting, is not that well electrically connected to your grounding/bonding system. There must be a good electrical connection between the zinc over the side and the metal you are trying to protect
