RE: So I've got a Rio EP...flexshaft won't fit.
That is the flexshaft I ordered. The tube appears to be perfectly fine, not squished at all. I will get the micrometer out and measure the diam. of the shaft and the inner diam. of the tube. I actually ordered two flexshafts and neither one of them fit. Both appear to be too big. The old flexshaft was ripped out of the motor collet and is sitting at the bottom of the pond lol.
