I have a pair of 3-blade bronze 19-spline props for my Arneson ASD drives that seem to have worked themselves loose at some point and worn out the splines. They slip on the shaft. I am using my back-up props and they are okay but would prefer to get these repaired as they better pitch/diameter for my setup.

Can these things be repaired? I'm in Fort Lauderdale area if it matters.

call frank and jimmies in lauderdale. if if can be done they would know. they fixed a lot of props for me back in the racing days.
