One of the routine maintenance chores that I do in spring is to tighten keel bolts. I use a 3/4" socket wrench with a 1 1/2" socket and a pipe extender. Then I torque as much as I can. It's a keel. They're big honkin' bolts. As much torque as I can apply is what I want.
With that said, Sabre recommends 90 ft lbs torque.
