Bronze prop with no anodes – what will happen?

[vyv_cox]

About 70 my of copper on the blades is said to last at least 5 years – we shall see.
Probably Trilux on the hub.

Interesting article.

I'm about to spend bedt part of £1000 on a prop, might be worth thinking about.

Thank you, I read it the other day, very interesting!
Has the plating been effective also during the last couple of seasons?

I should mention that where I am based, Swedish west coast, it seems at least a hundred boats have had their propellers copper plated over the last few years, following joint method development by the cruising association and a local electro plater. So I am far from pioneering in this field and feel rather confident that the result shall be fine. On the other hand, mostly fixed or folding props have been involved so far, feathering props are less common.
Here is a recent article on the subject (in Swedish, but you might get something out of it by means of Google translate or similar):

Sold the boat the following season. The prop was still good when hauled out.

I did not know about the Swedish story. I will try to translate it. Thanks.

My bronze Eliche Radice folding propeller has been on my 120S saildrive for 25 years. It doesn't have an anode. The outer hub and blades are separated from the inner hub and shaft by a large rubber bush (for shock absorbing purposes) so maybe this protects it?

More likely the rubber bush protects the sail drive leg from corrosion caused by the prop
