1987 OMC Manifold Torque Specs

[sylvanman]

Hello,

I just had to replace the head on my 3.0 Liter OMC engine. Does anyone know what the torque specs are. I found out that the head bolts are torqued to 95 foot lbs.

Thanks.

In my 1988 OMC factory shop manual, the torque specs are as follows:
cyl head bolts--90-100 ft lbs.
manifold bolts--20-25 ft lbs, working from the center of the head out to the ends.
