Gear case drain washer

Went to change the gear case oil on my 2016 150 hp mercury pro XS. The washers for the drain and fill screws look to be metal. I was expecting some type of rubber o-ring. Is that metal washer re-useable? Is it some type of crush washer?

I reuse them as long as they look ok, I have used an Oring when I was in a bind. Definitely the wrong application for an Oring though.

Thank you very much. I found some of the yellows on Amazon.
