Needs smoothed out, balanced and sharpen up the edges of the blades. Those chewed edges will create air bubbles and lessen performance. Gotta do your best to make all the blades match , then you might be able to get away with it..

Stainless Steel props are a whole lot stronger than the aluminum ones. Maybe that will hold up in your lake.

Yessir....when you strengthen one part, the next weakest will give way, just the law of physics... So which is cheaper, props or rebuilding the gears in the gearcase ?

The last time I had an aluminum 14x21 prop repaired it cost $80-$90, and it was in better shape than yours.
Since then I scrap the prop and buy a new alum prop. Pressed-in hub props cost +- $130. The last alum prop I bought has a removable hub. ....about $40 more. But the next prop will cost around $90 since I own the hub kit.
I always carry a spare wheel in case I have a bad pile up. Maybe consider using your snaggle tooth prop for a spare. It will get you home.

Agreed an aluminum prop is like a fuse.----Saves / protects the rest of the gearcase.-----But running with a bent prop is like running your pick up with tires that are not balanced.----Used to have a crew at work that was titled " vibration monitoring ".----They went around taking readings at exact same point on motors and pumps.----Scheduled bearing replacement before expensive things happened.

I used to run aluminum props on my 19' SeaRay I/O, in a shallow bay. The silt and sand was enough to rip 'em up, as she dragged her a$$ when coming on plane. I switched to SS and had no more issues. However, that bay did not have any hard stuff to hit with the SS prop.
