It looks like the removal of the old seal and installation of okie bushing is within my abilities. One question, and it's probably a silly one, but here goes: Having never seen an okie bushing as compared to a factory bushing, how can I tell if someone has already installed an okie bushing? I'm sure that wouldn't come out nearly as easy as the factory bushing. Here is a photo of my propeller shaft. You can't really see it in the photo, but the bushing currently there appears to be steel with a bronze bushing inside it. The bushing has tiny holes in it. It appears that there is a step (maybe the back edge of the bushing) about one inch inside the tube. Does this look like the standard, factory bushing?
