      The thick gasket under the lower cover cowling (#30 in the diagram) has disintegrated. It seems to be made from a soft foam rubber material about 3/16″ in thickness. The part is no longer available at MarineEngine.com, and my EBay searches have turned up nothing. I guess I could make a replacement but what material should I use?

      P.S. This is NOT the exhaust housing gasket. I have one of those.

        It will take some searching, but Grainger or McMaster-Carr should have something that will work.

            It really won’t make much of a difference if you leave it out.

              I believe  the only purpose of this foam is to help keep water spray out of the powerhead area and the motor will run just fine without it.  In all the years I’ve been working on these motors, I’ve yet to replace one and they don’t seem to mind.

                  If you do decide to make a replacement then I think neoprene rubber would probably be a good replacement material

                      A “soft joint” is the enemy of a properly torqued joint.  A gasket material that will compress and take a set over time (like rubber) can lead to a loose joint as the bolts lose clamp load.  My thoughts would be to use a good quality gasket paper based material that you can buy in sheets and make your own.   Some of it is pretty thick yet still difficult to compress.  Im still a rookie on these old outboards so “grain of salt and all that”.  However, I have a lot of experience with torqued joints and gaskets in general.   Good luck.
