Well, isn’t this interesting! 302035 is shown as the P/N for the ten horse lower bearing outer seal O ring and I can’t find anything in my Superceded Parts List saying it isn’t so it should be a good number. Searching that number brings up an O ring for the water pumps on newer motors. The OD of the ten horse crank bearing is 1 1/4″ while the sizes I find listed for the water pump 0302035 O ring are shown as 7/8 X 1 1/8 X 1/8. Is it possible the same part number is being used for the newer O ring as the original O ring with that part number hasn’t been used since 1963?
I think ME sent you the current O ring using that part number. Might be best to call them and see if they have any old stock with the same part number.
