    Looks like they were using the same part number in 1963.

    1963 Sportwin O-Ring on Upper Crank Bearing?

    Marine Engine usually show the superceded parts numbers, if any.

    If you have the old one, you could try buying a buna o-ring from a hardware
    or auto parts store.

    Prepare to be boarded!

    My 10hp (1959) original parts book sez 302035 is the number for the o-ring around the lower bearing and also for the lower end of the spacer. If ME is sending you the wrong size o-ring, their parts stock may be mixed up, wrong part in right stock box.

    Marineengine says that the carburetor on my 1981 Mercury 25HP is a Tillotson. Tillotson says it is not. So they are not exempt from making errors.

    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302035 is shown as the P/N for the ten horse lower bearing outer seal O ring and I can’t find anything in my Superceded Parts List saying it isn’t so it should be a good number.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.
