MerCruiser Alpha 1 Trim Tab Anode Hex Size?

[Jacalore]

Okay, trying to change the trim tab zinc sacrificial on my '85 Alpha 1 sterndrive. Every hexhead (allen) wrench I have falls thru the hole. It must be bigger than 7/16" - before I go to the hardware store, can someone tell me the size I need?
3/8" or bigger?
Thnx!
