      I am working on a 1952 Johnson QD13 and need to replace several gaskets.

      What material do i cut these gaskets out of? I know different parts use different materials so i am trying to make sure i replace with the correct material.
      How do i determine which thickness to use?

      Thanks for the info

        Well which gaskets? Some are different from others.

          Exhaust cover plate??
          Not sure if that is the correct name or not, exhaust side of the motor has two cover plates on it. One gasket is in between the two plates and the other is where the part bolts to the motor.

          Sorry if this is a bit confusing i am new to these old outboards and trying to learn.

          Thanks Nick

            Place an ad for the gaskets you want. Be sure to use the model number in tour ad. The gaskets that you are asking about are available. A lot easier that trying to make your own. In the long run it will save you time and money.

              Agree with Ed above. A lot of vendors that sell this stuff very reasonably! For the few bucks some gaskets cost, not worth trying to make, just my 2 cents. Rare gaskets, or easy ones are different.

                The exhaust cover gaskets have an important job to do and they were originally made out of an asbestos containing material. One edge of them has to keep water out while the other edge has to put up with the exhaust fire. Ordinary gasket paper would probably burn thru allowing water to enter the motor.

                I might have some loose exhaust cover gaskets in my pile but I know I do have complete NOS gasket sets going back to at least QD 14.

                  Will the QD14 fit the 1952 QD13?

                    YouTube has video about making gaskets. I bought a pack of an "assortment of gasket materials (4)" (maybe Permatex) from AutoZone and I enjoyed making two gaskets so far. My feeling is that this assortment of gasket material is much higher quality than my store bought OEM gaskets. OEM gasket looks like cereal box paper.

                      Sure you can buy gaskets, it may save time but not money. If yo are like me you fix motors because you enjoy . I make gaskets a lot and I can make a mercury water jacket gasket in less than 15 minuets.
