I take them down evenly and get them tight. No reason for a torque setting.

Do as stated above, But, let motor get to operating temp, let cool down completely, and tighten all bolts again. This will let the gaskets crush , the heat expansion will make some bolts loose when motor cools down. I do believe Merc says 30 ft lbs. although its hard to get torque wrench on all bolts if motor is in boat.
