LOL! Yeah ha ha! At the very least limit your prop to using the CF props there. Boat looks like it's running healthy. I figured you nicked it in rapids but looks like you have bigger problems. Find a new place or convert to jet. My props last indefinately unless something catastrophic happens (like in your vid) actually that's never happened to me. I know what you mean because I bought a 642 aluminum once and put the boat in the pond. I had to idle through some floating mulch and that's all it took. Boat wouldn't even plane off. CuBeTi props are much better but they don't like rocks.[:-]
