I have a PowerTech 3 blade 19p ss prop that was given to me when I purchased my boat. The hub was shot, so I pressed the hub out, and went online to try to find one. I decided on the Flo-Torq 2 prop kit as one of the websites listed PowerTech props to work with the hub. Well it ended up not working and I am trying to find the correct hub before I buy another one. I'll add a picture of the hub I removed.
