Hi group,
I have to change the head gasket on my 1989 mercruiser 3.0 engine. I have
ordered the shop manual but it is only due to arrive on Monday, and I would
like to have the boat ready for the weekend. I would appreciate if somebody
who has a manual could tell me the ft/lbs of torque and tightening sequence
required for the head bolts and the manifold bolts.
Thanks for your help.

Manifold to cyl. head: 20-25 ft.lbs.

Head bolts: 90-100 ft.lbs. (torque to 1/2 value and go thru pattern again
torching to this value).

On just about any gas engine you start in the middle of the head and make an
ever widening circle moving out.
