Not shiny like the picture, roughly made
I was expecting shiny smooth aluminum, like in the photo, like one expects to see with alumin. What I got is very mat in appearly, not remotely shining, or smooth. Instead it is roughly made, with ragged areaa that could cause injury to skin. Disappointed.

Perfect match!
Great shipping, packaged well, looking forward to see how well they perform this season on the shafts of the boat.

It is a valid anode in brackish water
Fits correctly. Correct voltage to a Ag-AgCl half cell. Bronze prop, will know more in 6 months.
