I am looking for the torque spec. and torque pattern for the head bolts and the water jacket bolts on my 1970 evinrude. If anyone happens to have that info it would be greatly appreciated.

Cylinder head 216-240 inch pounds

Other Standard screws:

#10 = 25-35 in lb
1/4" = 60-80 in lb
5/16 = 120-140 in lb
3/8' = 220240 in lb

Start in the middle and spiral outward. Tighten to 1/3rd first time, then 2/3rd. finally full torque spec.

Cyl head to be retorqued after running to operating temp and allowed to cooled comfortable to touch
