I have shaft zincs (2) as well as a zinc at the end of my maxprop. I have started to also put a large zinc over the side when on the mooring connected to the grounded system.

I noted that the zincs on the shaft are lasting much longer with this latest change but the prop zinc still disappeared quickly.

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.
