Re: Keel bolt torque values ????
Sabre recommends 90 ft lbs for a 6,800# keel. I'm pretty sure that it's a 1 1/2" nut on the bolt, but either way, I tighten as much as I can by hand while the boat is blocked. Close enough. On both my Sabres, I was able to get about 1/8 a turn on some of the bolts the first time that I did it. Thereafter, they've never budged.
If the bolt breaks from hand tightening using a standard socket wrench, then the bolt was going to let go anyway. The keel area is one of the most heavily reinforced areas on all boats. If the fiberglass crushed on a hand tighten, then the keel bed was degraded anyway and it's a blessing that you found out sooner rather than later.
