Volvo Penta 8.1L exhaust riser elbow pipe plug

Question: accessing/checking internal exhaust cavity without removing elbow

On our factory OEM Volvo Penta 8.1L TBI exhaust elbow (no CAT) there is a pipe plug on the top, almost centered over the exhaust riser. Does removing this plug allow "swabbing" the exhaust cavity for moisture?

I don't want to "un-do" a pipe plug that accesses the raw water jacket area.

We had the port engine exhaust riser gaskets replaced last year, and would like to check the std engine.

anyone remove this plug for inspections?

Searching on-line, I found video of removed VP exhaust elbow, which confirmed that 3/8 pipe plug on top does go to the exhaust cavity for swabbing the inside of passage for moisture/rust.

I'm going to try removing the one on my cracked elbow, as I have nothing to loose taking it out. That will let me know the issues accessing the others.
