Mercury Kiekhaefer 350 Twin flywheel reinstall

[jtwilson728]

Hello, I have a 1968 Merc 350, my flywheel has a decal on it that I am unable to read. It says something about "this screw in this location" or something like that. When I pulled the parts diagram for the motor and it shows two different part numbers for the screws holding the flywheel to the hub. Two of one screw and six of the other. Does anyone know the difference in these screws and why they are different?

2 screw holes can be used to pull the flywheel off.

Ok makes sense. Are they a different thread? I have the mercury service manual covering my motor but can't find anything about it in there.
