Obsolete Housing to Cover Seal OMC 308292

[caazi]

In the process of restoring a Johnson 1967 20HP and need to replace the now obsolete seal (OMC 0308292) in between the bottom motor cover and the exhaust housing. I have a sheet of foam gasket material that I am going to use to make the seal; what is the best option for adhering this, and on which sides, or both?

Attached is a picture of the original seal for reference

Thanks!

Just my first guess, but automotive weather strip adhesive should be safe on the foam. Most autobody stores carry it. Should say on packaging or manufactures webpage what mat’l it is safe for.

I replaced that same seal on a ’72 Evinrude 25hp and just placed a small dab of gasket sealer in 4 or 5 spots on the underside of the seal to hold it in place. Didn’t see a need to put any on the top side – once the lower motor pan is in place and bolted down, the seal is sandwiched tight.

Ha!

I found the old thread!

And!!!!! I found a place selling them for $5!!! Plus $15 shipping

Yea, I even called to check!

I ordered some ‘cause I’ve been working on those motors as of late, but they have four left.
But, if anyone reads this and has a good substitute, or knows what type of material was used in the original, please respond.
Im sure I’ll need some more At some point.
