This is the prop most often found on a Johnson or Evinrude 9.9 or 15 hp outboard from 1974 to end of production. I believe this is a Michigan Wheel replacement; the OMC prop had a plastic ring around the hub.  This metal one isn't as fragile.  In good shape as shown; all the blade tips are pictured; they have some small nicks but nothing you'd call a ding and it isn't bent out of shape. Shipping is as cheap as it gets via prompt and tracked Priority Mail.  Thanks for looking.
