      Wondering if anyone knows an impeller number that might fit
      the subject motor. It’s a “non-bailer” motor.
      I forgot to measure the height / depth of the impeller, but
      will do so today.
      Thanks.

        I re-measured the old impeller in the 10 hp Corsair, and it’s
        .500 shaft
        1.864 OD
        .580 ish thick

        I found one close in diameter in my stash, but it was way too thin.
        Hopefully someone has a proven impeller number that will work.

          In looking at old charts,
          Sierra impeller 18-3028
          seems to be a pretty good match for what I need, but it’s nowhere
          in sight on the Net. 🙁

          18-3028
          OD 1.860
          .500 shaft
          .602 height

            I used a Merc impeller in a Scott last year. The impeller hub ID was bigger than the driveshaft so I made an adapter hub. It worked real well.

              Thanks, PM T2- I’ll have to look through the charts again
              to see if that’s an option for mine.

                    Specs for that impeller shows that it’s an inch high,
                    and 3.6″ diameter…….. not even close to what I need,
                    but thanks for looking.

                    If you meant 18-3028, that one would work, but I can’t
                    find one “out there”.

                      I’m digging through my work notes but apparently I didn’t record a part number for what I used. As I recall, it was supposed to fit a KG7.

                      The Scott was a 1949 model 1-16.

                        Whoops!  I’m always accidentally swapping digits!  For 18-3028 everything I’ve found says it’s a woodruff key for a Yamaha.
