When winterizing last fall, we pulled what appeared to be a drain plug from the port side of the Outdrive. This is on the middle unit, not the gimbal and not the lower unit. It is mid casting. If you look at the other side there is a OMC logo and this drain/vent is on the opposite side but in the same location as the logo.
When we screwed it out, water came out. When we went to put it back it, it's like the threads have disapeared. All there is now is a plastic circle about 1/16 thick and no threads.
I find nothing anywhere on the drawings or in the manual showing anything like this on the side there. I am not talking about the oil fill/drain now that is elsewhere.
Can someone please tell me what this is and how to fix it?
