      Hello All,
      I found a starter bracket (203736) for this motor and it seems to fit fine. I don’t see this bracket number in any listings. I ordered an after market starter for this bracket and the bolt spacing was off about a quarter inch. This brackets bolt spacing measures 2 1/4 inch center to center. The starter I ordered measures 2 1/2 inches. Would anyone out there know of a starter that would fit this bracket. Thanks for the help.

        The 2-1/4″ bolt spacing on the bracket suggests the bracket was used on a motor originally equipped with a 6 volt starter. The 2-1/2″ bolt spacing on your new starter is the common spacing used on current 12 volt starters. Don’t know where you could find a 6 volt starter but you could probably find a good used correct starter bracket with the 2-1/2″ bolt spacing. I believe the bracket number you need is 317328 superseded to 126256. Here’s one link to a bracket and starter combination:

          Not quite sure what you are working on, but that bracket is not for a 1970 Johnson 20hp, it is for a 50s model Evinrude 15/18hp…

            It was advertised with these numbers which should have worked. 317328 308482 320012 304767 0304767
            All the mounting hardware fit pretty well. Just hoping to find a starter to fit it. Seems half the stuff I buy anymore needs sent back arghh!
            I should have checked the numbers when I received it.

              Unfortunately, you can’t count on numbers provided by sellers, not that they are being dishonest, just not well enough educated. You shouldn’t have much trouble finding a starter and bracket for that engine, not that uncommon…
              I don’t have a 1969 accessory book though…Please be sure your engine is a 1969 model though, did you post the model number?

                Those starter brackets go for a pretty penny!!!

                Marineengine.com has the accessories listing for 1972 and later years for the 18, 20, 25hp.

                  They are expensive.

                    The seller said it came off a 18hp. I don’t think the seller was dishonest just a mistake. The starter that came with it is a Auto-Lite MDH 4001M 12K. When I look that up I can’t make much of the information. The starter guy said it’s not worth fixin. The motor a Johnson 20R-70C is one I like to bang around in. Nothing I am trying to restore just trying to get the pull factor out of it Ha! If I could find a starter for it I believe it would work. If not I’ll just ship everything back and start all over. Season is about over anyway.
                    No Hurry.

                      Ship it back, you have all winter to find a decent used starter and bracket at a reasonable price… We have to find a 1970 accessory catalog to get the proper part numbers for the starter and bracket….

                        I can relate. My right shoulder is starting to be bothered by starter rope pulling. No immediate discomfort but later on…. Seems it’s time for a starter on the snowblower too. I’d like to find a starter and bracket for my ’69 (?) 25 hp.

                        Do Prestolite and Auto-Lite starters have the same dimensions?
