Lost shaft zink anode during season, prop is corroded like f....

I keep my prostar in the sea(salt water) all season. When I took it up for the winter now I noticed that the zink anode on the shaft was gone, and the propeller was corroded quite a bit. I havent checked the nobleness of the material in the prop and the shaft(galvanic corrosion), but the nibral prop is clearly protecting getting sacrificed and protecting the steel prop shaft without zink.

So If you keep the boat in water, at least salt water, put a zink anode on your shaft, otherwise the prop itself seamingly get sacrificed.
