      Can Someone direct Me to a site that has a parts breakdown for a
      Johnson SD20?
      I had a parts list somewhere and can’t find it 😥
      Thanks for any help.

        I assume you’ve seen this?

        http://mahoganybay.net/store/components/com_jshopping/files/filesproducts/1950%20Johnson%20Parts%20Catalog%20SD-20.pdf

        It’s linked as an SD20 manual, but the text is titled for the QD-12. Are the models highly similar, or is this just a goof by mahoganybay.net?

              Steve,

              I have a parts manual for my SD-20. I have not scanned it yet, but I could probably get a copy in a day or so if that would help.

              Just got mine going tonight.

                Thanks for the offer, but I have a hard copy, somewhere.
                We moved last year and everything is still a mess.
                In fact I’m still moving My shop stuff.
                I’ll find it. I just wanted to find the part numbers for the rubber mounts
                that hold the shroud on.
                A couple of them are broke. So I figured I’d look for some.
                I know it’l probably be a needle in a haystack type of search.
                So anyway, don’t go out of Your way to scan it.
                Thanks.

                  Steve,

                  Part number for side mount is 45-302021, and rear is 302116. Probably do not need the "45"

                    I’ll start My search now.

                      Steve,

                      There was a bulletin on those mounts to upgrade to the later style mounts from the Evinrude Big Twin for instance.

                      The originals are vulcanized at the rubber/aluminum connection and don’t hold up. I replaced mine on the SD and my QD motors as a result. Besides the later big twin style mounts are easy to find.

                        I was hoping to talk to You at Constantine,but I didn’t see You there.
                        What years of Big Twins are You referring too ?
