force exhaust plate

[Kerr1e]

I have a 1998 120 hp force. Does anyone know the torque spec and bolt sequence for the exhaust plate

80 inch pounds. Start with the bolts in the middle of the plate and work your way out towards each end of the exhaust plate.

Just to reiterate, INCH POUNDS. Many people have tried this and come back to report broken bolts before reaching the required torque. Come to find out they were torquing it way too much than required. Also make sure you do it in two or three steps torquing, i.e. torque all bolts to 40 in-lbs first and then followed through again with 60 in-lbs and finally 80 in-lbs.

Thanks. I have replaced power head gasket and head gasket. And milky substance in bottom 2 spark plugs and bottom carb. I don't know what else it could be except cracked head

After replacing the exhaust plate gasket see if the same milky substance is still there.
