The warranty slip that came with the prop recommended having the prop repaired by a "qualified trained technician," a locator for whom could be found at nmpa.com. I spoke with one I found in NH, and he advised me to throw the thing away. He said that too often the process of replacing the hub internals results in a crack of the aluminum casting. His price was $100 total, which would be wasted if the attempt failed. The prop cost me only $134 with shipping, and the same site has the same price now.
The technician suggested I "upgrade" to a carbon fiber composite prop from Piranha. They don't have a rubber hub to fail, and a broken blade can be replaced by itself, by the owner. And he just happens to be a Piranha dealer! I can get a "close" size replacement for $165 + shipping. I'm mulling it over, and any advice, taken or not, would be appreciated. Part of me says that the chance of an exact replacement also failing is very low, and the other part says that so far my results with that mfg/model is 100% failure rate.
