Looking for Torque specs?

[mnm99]

Can someone steer me in a direction for torque specs for an 8.1? I looked through all my manuals and cant seem to find one. I go online and can't seem to find a good source. Looking for manifold / riser specs...Thanks

Edit--- I found a Mercruiser manual online. It says 26 lb-ft for the manifolds and 15 lb-ft for the elbows. Sound right?

Here is what I found in my copy for 350's service manual #28.

Fastener Location lb-ft
Hose Clamp Securely
Exhaust Elbow or Risers to Manifold 33
Exhaust Manifold to Cylinder Head 25

Those are for a 350. I found the ones for 8.1. Thanks though...

Run a tap through the manifold to riser holes and get the paint out of them.....I think it was Ron that cracked two new manifolds because of thick paint on the threads....
