Please explain how it should be installed. Should it be on a deck
or on a bulkhead? Where is it typically located and oriented?

Is there a net accessible photo of something similar and installed
properly?

Are you sure it is BRASS?

If so and you are in sal****er, forget it.

Find a bronze one for sal****er.

BTW, what is the hull material?
