Can you email the photo to me I cannot quite tell from the photo you have posted. Is it pitting or does it appear to just be on the surface?

It is several thousanth's deep. Lines are forming and they are getting longer and deeper. I'll try to get Donna to e-mail them. I'm at work and they are on home puter. Thanks.

This does not appear to be cavitation burn.

First, it is on the low pressure side of the blade. Cav. burn happens on the face or high pressure side of the blade.

It looks to be build up rather than pitting. Lake Erie has the water make up to causes this type of mineral build up on propellers all the time.

If it is a mineral buil-up, it is very metallic looking. I tried to sand it smooth once with 280 grit wet sandpaper. Didn't work. Too hard. And it is only this prop. The port prop is still shiny. Not arguing just trying to give as much info as possible. Thanks.

If its just build up on the prop try Lime Away. Dont sand your prop what ever you do. Hard water stains will come right off with non abrasive Lime Away. Dont sand it, steel wool it, scrub with a scouring pad, anything abrasive will ruin the finish.

I used acid based mag wheel cleener on the prop before taking the picture, just to clean it up. No sign of calcium. Steel wool won't touch this.
