New to me boat purchased last summer in Ontario Canada. Seller and surveyor were unable to identify the anodes. As soon as I got into salt water I checked the hull potential and is was -200mv.
At least everywhere in the bonding system measured the same within 5mv or so.
I tried wire brushing the anodes without success so used a hanging anode which dropped the potential to around -600mv until I could haul the boat.
It took a hammer to expose base material.
It's zinc not aluminum.
This is what the transom anode looked like:
