Inline flywheel torque?

[cvx16]

Does anyone know what the torque is for the flywheel/flex plate on a 1977 merc inline 150? Can't find it in my manual, and would not like this to come apart unexpectedly. Thanks,
Bob

Should be around 80 lb/ft, or use an 18" breaker bar and pull it "TIGHT".

Just to make sure that we're talking about the same thing. The 5/16" fine thread bolts, (8) of them around the big nut in the middle are torqued to 80 ft/lbs? Thank you for your time, Bobby
