Re: BENT SHAFT AGAIN Pics needed. Sounds like you need to either beef up the structure or add support to the shaft.

Re: BENT SHAFT AGAIN The outer shaft is 1/4 inch steel tubing. I keep bending the 3/4 inch prop shaft.

Re: BENT SHAFT AGAIN 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.
