      I have a pair of Johnson A’s I’m working on.  One is 1922 and the other 1924.  The earlier one has screws holding the steering bar to the cylinder heads.

      The 1924 is missing the bar. Later motors (e.g. A-35) would have studs in the cylinder for the bar to set on and then secured with nuts.

      I pulled these out of a junk jug thinking I’d use them like the later model but now I’m wondering what was “right?”  Did they use screws originally, like my earlier motor?  That’s why there are no studs in the 1924? When did they switch over?

      More silly detail questions to follow.  : )

        I looked through my picture files and the screws
        seem to be corrects for the A & A-25. Studs appear
        on the A-35 going by the pictures I’ve saved.
        There are a few exceptions but parts do get moved
        around over the years.

        A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.

          After posting I looked at the motors I have had.
          This A 25 looks to be original and it has studs.

            Here is something to add to the confusion.

                Johnson changed from screws to attach steering rails to studs and nuts beginning in early 1925. An early 1925 A-25 would have had screws but a later 1925 or 1926 A-25 would have had studs and nuts, however there would have been some overlap.Your 1924 A would have definitely had screws.

                  The serial number of the motor I posted a picture of
                  was in the 42.000’s making it a 1926, inline with
                  Stanley’s verification.

                    I’ve tried three times to post a question about the tiller handle.  After lots of time transferring and uploading photos and adding text, I get this, and then it’s all gone.

                      Anticipating your question,there is a 2 part (w/slotted screws) aluminum casting that clamps onto the steering rail.The tiller tube is attached by a large river to the casting.The tube and steering rail on all pre 1924 motors are plated steel.The 1924 model A both were plated brass and1925  A25 was also.1926 was plated brass steering rail and aluminum tiller tube.All came with leather/wood Bulldog grip.

                        Stanley, you know so much about these early Johnsons!  Thank you for sharing what you know.

                        My 1922 has a nice leather grip

                        I picked up another leather grip at a swap meet. It has a wooden piece inside of it.  I pulled the grip off the 1922.  No wooden piece.
