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.
