Howdy, Southpaw.<br /><br />Is your impeller the type with the sliding vanes? I didn't think those would ever wear out.<br /><br />When I had a 7.5 Elgin, back in the 70s, I was able to get parts through Sears.<br /><br />If you have no luck there, try <br />www.twincityoutboards.com<br /><br />They have almost anything.<br /><br />Good luck.
I used to have a 7.5 Elgin (still have the parts list). Part number appears to be 73055; you'll need two. I got parts years ago from:<br /><br />McCulloch Distributors<br />3829 McCormick Road<br />Riviera, AZ 86442<br /><br />Good luck!<br />Lewis
