Hey Guys,

This is my first post here so hopefully I am in the right location. I will save the introduction for a more suitable location. I have a 1953 Evinrude Super Fastwin 15hp. I have been doing some work on it and decided to pull the cylinder head, exhuast port, and intake ports. My new gaskets should be in today and I am going to get her all put back together.

My questions is, what is the torque spec on the bolts and is there a specific tightening sequence for the cylinder head bolts, exhaust port bolts, and intake port bolts? Thanks in advance for your help!

Cylinder head, 120-125 INCH Pounds. Other screws #10 = 25-35 in lb, 1/4" = 60-80 in lb, 5/16" = 120-140 in lb, 3/8" = 220-240 in lb.

Start in center, spiral around to outside, tightening to half torque, repeat at full torque.
