Opinions needed on impeller damage

[Sixty4Fairlane]

Long story short, someone riding the spark got too close to the shore in the lake and sucked in some rocks. The wear ring is ruined but that's the least of my concern. How bad is the damage to the impeller blades? It doesn't look good to me but I wanted another opinion. What would happen if I just replace the wear ring and call it a day?

Its very salvageable,,,I have been cleaning up edges like yours for years,
I put the prop in a vise, and use a cold file.,,that is about 1,1/4 inches wide. If there is a bent edge, I use an adjustible wrench to bend them back,,,If there are no bent edges, I file down all the rough edges from the side of the blade,,,then I take the file, and go over the curved part of the blade,,,in long arcs from the exterior to the centre hub.
just make sure to NOT go over the curved edges that touch the wear ring,,because that will increase the spacing and cause cavitation,
It really comes down to experience, having used this method for over 20 years,
I wish I had pics for you.,,,I will try to send a pic of my file,,,same one for years, For finishing work you can use a finer file,a smaller file near the hub,,,or some narrow finishing air tool.
The cold file prevents over grinding and heating the metal reducing its strength.,,that air tool is great for finishing.
This will work for aluminum or stainless props.

Thanks a lot for that detailed reply. I definitely feel much better about it and I'll be taking that approach tomorrow when my new wear ring arrives. I'll be sure to update.

You actually want the top edge of the non-wear side ring side of the prop to have almost a rounded almost flat surface,,,a slightly rounded surface instead of super cut your finger sharp will not wear away at the top edge of the prop,,,
Yup,,, your prop is easily repairable.
