Torque for exhaust manifold?

[olddogmike]

I just installed a new exhaust mainfold and riser elbow on my 1995 Mercruiser 3.0 LX. I checked in the Mercruiser manual but can't find the torque values for the exhaust manifold bolts or the riser elbow bolts. Would apreciate any help that you can give me. Thanks.

The book calls for 25ft.lbs on all these bolts....

For whatever it's worth Osco recommends retorqueing those nuts after you start her up and run it for awhile.<br />Rich
