I bought a 2004 J109 last year and it came with a brand new unused replacement anchor roller. I can't figure out how to securely attach the roller to the stem fitting. There are bottom holes that line up over the mushroom buttons, but I don't see how to bolt the roller to the fitting flange with the given hardware. Perhaps something's missing, or this is a roller for another type of J-Boat.
Could another J109 owner walk me through how they do it, or, even better, send a photograph of how their anchor roller attaches to the stem fitting?
