Re: johnson 115 (maybe spun prop)
First off, make sure it is spun.<br /><br />With a permanent marker, draw a line on the prop outer hub and a corresponding line on the prop inner hub.<br /><br />Run the boat and see if the lines stil match up. If not, it's spun.<br /><br />Re hubbing a prop is NOT a do it yourself proposition. A prop shop needs to do it.
