Base timing 4.3?

Think I’ve researched and got the answer but new someone here could verify.
1992 4.3L Mercruiser/Alpha TB-IV
when setting ignition timing just verify idle speed, shoot with light and adjust? Nothing to disconnect, ground , or jumper for base timing mode? I ask because this boat was setting at 0 instead of 8BTDC.
