Yes, but it's like a hammering a rivet, a small object's mass vs a large object's mass to get the desired effect. If you look at mass of the tranny versus the nut its got to be at least 300:1. So 1/300 of the 325ft-lbs is about a foot-pound. Not to mention the tranny was loose in the housing and I held the shaft with my hand, it was just little bit of vibration.

Now imagine similar frozen nut on loose big bolt, the mass ratio would have been more like 10:1. Holding on to that with my hand would have hurt. ;^)

IMO, we do far worse things to the tranny when we reverse into the slip to slow the boat, than using an impact drive on the nut. Sometimes, mass is your friend... but not when pulling into the slip.

YMMV
