Mercruiser 3.0 exhaust manifold torque settings

[Patboat]

Hi everyone, Does anybody know what is the torque settings for the eight small screws from either side of the mercruiser 3.0 exhaust manifold (that fasten the blanking plate at the right, close to the exhaust elbow and from the water intake at the left). The workshop manual doesn't mention it.
Many thanks,
Pat

You would use the SAE torque table for the specific bolt/nut. In the chart link, select grade/type of material its made of and then look at size and if any lube or sealant is used.

I would just use a small wench and set my elbow, just needs to be snugged up, not much pressure there

Thanks, I finally setted my elbow as per your recommendation, as I found the torque table a bit complicated
