freeze plug size for Volvo Penta 5.7 Gsi

[pvancorenland]

What is the size for the brass freeze plug (part # 3850802) that's used in a VP 5.7 GSIPEFS?
I believe it's 3/8", but I would appreciate some confirmation.
I'm not 100% sure if freeze plug is the right word. I am looking for the brass plugs (4 total) that you remove for winterization. I stripped a few heads on them.

It's just a pipe plug, not a freeze plug (aka core plug) it's a 1/4"NPT brass pipe plug.
I did check out the part number to be sure what you were talking about.
