I bought a 9x10.5J prop for my 1977 9.9. It's the same except for the shaft that it installs on is a bit larger and shorter on my motor. What will this prop fit? I assume it's a newer johnson 15 horse, but not sure. I gave $20 for it and it's in good shape w/ most of the org paint. I cleaned up the edges and need to get rid of it, but not sure what it fits. It is "exhaust thru" and like I said, Identicaly to my 9.9 prop, but needs a narrower, longer shaft.
