Quick update. PYI quoted me $750 for refurbishing my Max Prop (that a local prop shop said was "shot" and beyond repair) which included new cone gear and spacers, plus all the hw/fasteners to re-assemble. PYI said the prop was in better than average condition, the blades were very "thick", and would last many more years. That will teach me to take a max-prop to a Vari-Prop dealer for service. But tbh, kinda shocked the Vari-prop guy would be so dishonest in the interest of selling me a new prop. Looking forwards to getting my now, "like new", prop back from PYI!
