1993 Mercruiser 3.0 exhaust manifold.

[kcmedic271]

I'm looking for the torque specs and pattern to tighten down the exhaust manifold on a 1993 mercruiser 3.0 motor. Any help would be great. Thanks in advance!

The manual states to torque to 23ft lb and tighten from the center and go outward. Normally tighten in three passes increasing torque as you go.
