Pics needed. Sounds like you need to either beef up the structure or add support to the shaft. |

The outer shaft is 1/4 inch steel tubing. I keep bending the 3/4 inch prop shaft. |

I have a 3/4 inch nut, a 1/16 inch brass washer and a 1/16 inch trush washer between prop and bearing housing. |

Stop hitting logs? Put 1 nut and 1 washer above the prop to the bearing. Keep the distance from that nut to the bearing housing less than an inch distance. Should do the trick. |
