Commonly called "Blubber valves" due to the sound they make at idle.
They are used to act as check valves over the idle relief ports in the outdrive.
They help idle rpm by letting the exhaust out early instead of going out the back of the drive.

they did that occasionally, no worries. try to replace them if you get a chance but its not a big deal.
later stuff simply had a hole.
