3.0 manifold replacement

[rparde]

Hi,

I am replacing the manifold and elbow on my 99 Bayliner with the 3.0. Serial number is L374668. I am trying to find out what torque to use on the manifold and the elbow bolts. Additionally, should I use any perfect seal or anything else on the new gaskets or just bolt them in place? Thanks for any help.

Gaskets go on dry (ENSURE you use Merc genuine gaskets!).

Manifold to head torques are, for the centre bolts 20-25lb-ft, outer bolts 15-20lb-ft, re-torque after 20 hours.

Exhaust elbow bolt torque is 20-25 lb-ft.
