OK. I'm giving up on the local prop shops. Base on the e-mails, I'm going to buy a used prop and take it to a regular machine shop and have them bore the prop for a ISO Metric Taper 10:1 on a 25mm shaft.
Should that work?
Or do I need to give them more info?
Where do I buy the metric prop nuts?
I've managed to figure out that the prop should be a 12 x 7 fixed three blade.
Thanks for the help so far.
