The worst stuck prop ever!

[Robsauto2]

I don't get it. I have removed props 100 times before and never had one like this. It was a 14/24 dyna, it has a washer and grease on the threads. We even used a torch and it went maybe 1/2 turn and locked up. Thats my tech Dave bouncing on the wrench trying to break it loose, he's 6'3" and 250+ pounds! Needless to say, I destroyed the prop, shaft, 3 removal tools, and the stator was already damaged from a rock, so anybody got a good used gpr shaft for sale?

I know the feeling, I had one that was so bad that after I broke half my tools Including a 5" bench vise I sent it to WFO and let him break a few of his tools as well. I never did ask him what he finally had to use but he said it was'nt pretty. Neither was the prop, but that was expected.

I have had two vises break , these props are tough !!

I did one for InsandiegoJoe he had run it one outing only I thought it would never break lose when it finally came off the washer was pressed up over the outside of the impeller where the threads are never seen anything like it before. In my opinion this did not happen like this with the old style washer I believe the end of the impeller needs to be relieved to clear the small radius on the shaft. or a small spacer needs to me made to keep them from binding.

Rob I do not have an extra shaft but I have a loaner sitting on my bench. I will not need it for a month or so its yours if you need it. I will set it out on the front porch so you can drop by and pick it up. I am off to work early and will be working all weekend.

to help prevent this always use anti seize and always put it on real right - when I put it on I also stand on the wrench - this means it won't spin on tighter on you

to get it off I always use the stand on it approach - i simply stick the wrench with the drive shaft holder tool under the drivers side front tire of my wife's van (shhhh don't tell her)

Did you have a nose cone on the prop?

OH MY GAAAAAWWWWWWD....I am having the exact same problem. Just bent the crapola outta my shaft and destroyed the stock impeller. Gonna try cutting it off next just for S&G's. I gotta see what and why it isnt busting loose. That quarter turn either way freaks me out and I just gotta know why why why.

Rich just had to cut one in half for Porksord. I think we need to see if this is related to the upgraded Yamaha washer. Was this happening so much with the old style washer with the rubber sleeve?

I use a plether of antiseeze on everything and torque the prop over 50 pounds which I know is to much. Never do I have issues with prop removal. Not bragging just thinking out loud.
