Where is the overboard discharge valve on '79 yacht fish?

Depending on how yours is plumbed there can be several. On mine there is one in the aft stateroom behind the dresser in back of the head. There’s another one in the strb engine room forward in front of the engine, and another one up by the holding tank in the forward bilge.

Thanks a million!
