I can’t say for sure if the cover is stainless or not. But you can tell simply looking at the edge, between the gaskets. If it is thin, about like a credit card, it is stainless. But if about 1/8′ thick, aluminum.

Good luck with your motor. It sounds like you know what you are doing. I live here on the Gulf Coast of Florida, so been there, done that.
