call Bob Lipton Performance Props 636-949-3121. St. Charles, MO. This was from another post. Sometimes we get some prop repair guys who want to get business off the board. I have heard he is good. Others would be Port City Propeller Service in Fort Smith, Arkansas. Hydromotive Props in Ohio. There is also another in Louisiana that some of the regulars on here use as well, dbasketman may know that one. Also depends on what you are looking to do and what goals you want, what setup you are using. The PVS system is a great starting point to tinker with before spending $$$ on tricking out a prop. Good luck!96 Eyra/12 Mercury 175 Pro XS with 2015 single axle trailer2017 Victory Gunner
