I don't know if foot/lbs, but mount it tight where there is no movement. I doubt that you will overtighten it to where you are crushing the transom anyway.

Good and darn tight...then double-nut it so it don't vibrate loose(which is highly unlikely anyway)...

I would get a manual jackplate. Then you can go up and down much easier.

Gooten Tite is good. No need to torque the hell outa em. Ya to play it safe use lock nuts or loctite or double nut em. Though personally I've never heard of one falling off.

Fyi it IS possible to crush a transom by overtightening the motor bolts. Not a new/sound transom mind you. But y'ought see the damage a couple rednecks with an impact wrench can do to a soggy one.

If you have a Johnson or Evinrude, the mounting bolt torque is 40 ft. lbs.

Use nylon locknuts and make it nice and snub. As long as there is no movement, you are fine. No need to stretch the bolt with torque.

Tightening them that tight,I'd replace them unless they're grade 8 bolts. It's possible to stretch a bolt,making it prone to breakage.
Over tightening a bolt can be worse than under tightening.
