I completely agree with Russ. In your pictures I saw 3 anodes. The oldest of them quite close to the strut. Some people do this to prevent the shaft from falling out of the boat in the event of some catastrophic failure at the coupling in the boat. Being as close as yours is may obstruct water flow to the cutlass bearing so moving it back a bit might be appropriate. 3 anodes are completely unnecessary. I would remove the oldest one since it is old anyway. Remove the forward most new anode and save for later. When installing them make sure to tighten evenly and have a hammer nearby to give 'em a good seating blow on both side a couple of times. Strike upwards in line with the strength of the strut to oppose the impact.
Bonus points: I use electrically conductive grease, like that used in house wiring when working with aluminum wires, to help create and ensure a good and lasting electrical connection.
