1993 malibu echelon mercruiser 350 magnum tournament ski

I have been trying to get this boat running after sitting for a few years. Noticed an empty tapped hole above oil filter, wondering what goes there or if it should be plugged?

Any ideas?

Nope, if memory serves me right i'm pretty sure it can remain open as is, plus the service manual showed it open as well.
