    Default Evinrude Piston Rings

    I am puttting new rings on a 15hp 1977 Evinrude. I see there are 2 different rings. one is shiney and the other is dark almost black. I have not seen this in smaller motors and do not know which ring is the upper and which is the lower. My service manual does not say anything about this. Can you help?

    It should be obvious if they are original type rings.------The one with the taper / angle is the upper one.

    I will get to the shop and check, I did not take them out of the package just viewed them through plastic in case I had to return them. If I had pistons out I probably would have seen the difference but I got ahead of myself. Thanks

    I also have A 1986, JCOCDR. Iím putting in new standard rings. Both rings donít seem to have an up or down orientation and they seem identical. Did you find this to be true as well? Thx.
