I wish I could find the under water video that explained the noise. There was a considerable difference in sound between prop nuts. Sure they could have edited the video but it was a softer sound. The red ones will fade over time. If nothing else it does make for a quick prop change.

I bought it for convenience... Easy to remove the prop and check for fishing line... Dan

I like mine and it is on a Motorguide.

mine did the same, kinda hissed me off its only couple yrs old on a garage kept boat.. I guess we can re-powder coat them Ronnie..

I ran one for a long time but one day I decided to take it off and see if I could hear a difference. It stayed off after that. It seemed to make any little wobble worse which is weird because you would think it would have the opposite effect because it's putting pressure farther out on the prop. I still have it and may try it again later. I did see that video mentioned above. It was a guy in Australia I think with a different brand but the same thing.
