I have a '92 Manual 25 HP Merc, 0D248099. I pulled off the prop to find out that the thrust hub assembly is chipped and appears to need replacing. Does anyone know if this part is easy/hard to find and replaceable? When I go to mercurypartsexpress.com the part is "n/a" at all regional locations. It appears from the manual that I will need the bearing carrier tool to remove this. Is this correct? The manual explains of another alternate method for removing it by use of the "...thrust hub that was removed during the prop removal procedures". Although the only thing removed previously was the propeller nut and prop. So I don't have a "thrust hub" according to the motor's diagram. I need to go ahead and replace the oil seals anyway so I guess purchasing the tool will be worth it. Thanks for the help in advance.
