I received my prop back from ACME today. They had it for one week so including shipping the whole transaction took 1.5 weeks. The prop looks good and is back on my boat now. I will not get a chance to test the performance this weekend, but I will update again with results.
For now I can say everything looks god. Most all the machining grooves are gone from the grinding done during balancing, but all the blades look to be true. In total the repair with shipping to/from ACME cost me just under $130... Not bad considering my local shop wanted $160. Granted that was a price quote for site unseen repairs. It may have been just about the same price. Now I just need to see if it runs vibration free, then I will eventually get my back-up prop fixed as well.
