I had my prop worked on by a shop outside of Waco Texas. I see you said you had yours worked on by a place in R.I., however you could mail your prop and have it repaired. The name of the place is Performance Propellers, formally Prop Dr. They do quality work at a reasonable price. I had some bent blades repaired on steel prop and I believe the cost was around $65.00. They balanced the prop, and my boat never ran better afterwards. If you are interested in the number, it is, 254-932-5550 owner Shirl Zwicky.
