Does anyone know what Mercury recommends to TORQUE them at ???????

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.

Do as stated in post #2 and #3. Good addition partner!

And still check them periodically!!

....and don't forget to have her polish them without getting inside the bilge....

It`s 30 ft/lbs torque ? , where i can find info on how much torque to apply ?
Thanks to take time
Regards

Mercury 525 manual says 30lbs.

Others all mentioned good points.
