Coupler bolt torque values?

[rdc54yty]

The engine is a 3.0L Merc w/Alpha 1 stern drive. Anybody know what the torque values are for the 3 coupler bolts. The Merc manual procedure for removal/replace of the flywheel says "See Table 2" for the values. Table 2 doesn't list coupler bolts. Thanks.

Thanks again. Did you get that from the General Values Table for Grade 5 bolts? I tried that and twisted the bolt off. Maybe just a bad bolt.

Thanks, that would explain the twisted off bolt lying here on my desk. I guess I'll save my lunch money an by a real set of Merc Mans.
