Hi Lloyd,
Sounds like you have a good mechanic.
Good practice for fine work or critical assembly is back off & re-torque but
it's unnecessary for keelbolts. And is the spec for dry & clean or lubricated?
We just need them "tight enough", 10% over is no big deal. I would check each
at spec then try again at 10% over on any that prove tight on first go, but
stop at movement.
But only 250 ft/lbs?... have you got 3/4 bolts? 1" should be 350 ft/lbs.
I'm surprised he didn't suggest a torque-multi as Jim did. If you use an
extension on the socket then you need to compensate for that torsion as well
(depends on the length of the extension).
KISS, we're closer to farm equipment standards here than race cars. :)
Cheers, Russ

Hello Listers,
While on the hard want to check the nuts on the keel bolts and understand
250 lbs is needed. Boat mechanic says it is very difficult to get the proper
leverage deep in the bilge. Anyone ever used a small jack and maybe also with
a cheater pipe to apply side pressure against the bilge walls to move the
torque wrench.
Also, mechanic suggested slightly loosening the nuts first and then
re-tightening. That does not sound good to me. Any thought on his suggestion.
I thank any responses in advance.... always appreciate the help.
