I recently bought a turning point prop that's 13 1/4 x 17 to replace a 19 pitch in the same diameter. The third time out I was in 30' of water and doin bout 30mph all of a sudden the prop lost a blade. I didn't hit anything, its as if the seam pulled apart where the blade meets the hub.has anyone had any trouble with this or did I just get a lemon? I emailed turning point and I sure hope they can replace my prop. the other two blades don't have so much as a scratch on them.
