1983 Johnson 115hp tilt and trim adding oil

[DeepCMark58A]

So I am doing my once a year add oil to the tilt and trim and in the bleed screw when I loosened a snap ring came out. Question does the snap ring go in before or after the screw? Do I need remove the purge plug to reinstall the snap ring or does the ring prevent the purge plug from falling out?

Never mind with a head lamp and my cheaters I see the groove, logic told me there would be no reason to have a snap ring under the screw but now I know.
