Neighbor had a merc hub prop I wanted to test out on my boat(yamaha). My stock power tech is a 13" 19 pitch, this it a 13 3/4 15 pitch solas titan, but has mercury hub. It will fit the spline patter, but i want to make sure I have the right thrust washer and all. Little gun shy to try something on a high dollar engine and risk screwing it up. Should I just replace with a yamaha hub and get the proper thrust washer and all? That's what Im leaning towards just to make sure its all correct, but I know less than nothing about props. Some have told me its fine to run, but its not their boat and I want to do it the right way. Any input appreciated
