Mercury Mark 78A timing

[bluekatblue]

Currently in process of restoring a long time stored Mark 78A.
The timing belt is on order (mer #20140) and should be in a few days and I will start removing flywheel and stator. Where are the timing marks located and what procedure to follow in setting proper timing?
Any help will be appreciated.

I looked and didn't have a service manual that goes back that far. The best I can remember you used the double dots on flywheel but can't say for sure.
