A friend of mine that asks me for help on his rc boats a lot, just hit me with this one. I have never seen this before. His octura x642 prop, the leading edges are getting folded over. he calls it flatting the prop. He is running a genesis with a leopard 4082 kv1500 on 6s with a 180 amp esc. He is not over revving it. I am wondering if the shaft is too high or low causing cavitation doing this. Water is a very powerful substance.
