Can't find a part for my 1961 Evinrude 18hp

I've looked everywhere and I haven't been able to find the upper to lower gear case seal for my 1961 Evinrude 18hp. The model number for the motor is 15034 and the part number for the seal is 302513. Apparently it isn't made anymore. Can anyone help me out!?! If I can't find it I guess I'll try to find one the same size for a newer model, but that may not be possible. I'm open for any suggestions and ideas.

Thanks!

found these, don't know if it's what you want though.

All seals are still available for that lower unit. Go to any Johnson/Evnrude dealer and have them look up the seals on their Microfiche reader and transfer over to the computer look up screens. Many of the original part numbers have superceded to new ones but they are all still available.

And if that doesn't work, get a piece of gasket paper from any auto parts store and make your own.

Use 3M Scotch-Grip 847 Nitrile Rubber Plastic Adhesive 5 oz. Tube seal the lower unit. It is the replacement for the Sealer 1000 that was originally recommended by OMC.

Here is a link to if you wish to order some. Very good product and takes very little. So you have plenty for many lower unit seals if you store it away properly.

Here is a link that will give you a good idea how to do it. Not your exact lower unit but close enough.
