Bronze prop pitting
Some prop advice needed please.
My bronze prop shows pitting as per photo. Is this caused by corrosion/electrolysis? Or marine growth? And should it be repaired? Is there some epoxy type of fairing that one can use?
Cheers

Re: Bronze prop pitting
Must be cavitation! Your prop speed is to high, pulling bubbles that collapse at the speed of sound in water causing this pitting.

Re: Bronze prop pitting
The pitting is evenly distributed on the front and back. I'd have thought that cavitation would be more on the back?
Can one repair the pitting DIY?
