It is not going to break. The yield point is a substantial percentage
of the stress at which it would break. It it bends sitting, it would
break the first time you hit a bump.


Question is will my parking it with a floor jack under the center bent
it back over time.


No. See above.


Really? *Cause it bows up about 3" in the center when I lift the
entire trailer and boat from the center of the axle with the floor
jack. *You're saying that doesn't matter, that's not enough to bend it
any. *Even if I do this for cummulative months?


Did I understand you right - it bows a full 3"?

There is no way it should flex a full 3" and that is probably your
problem.- Hide quoted text -

No, you don't understand. It only flexes up when I put a floor jack
under the center of the axle and jack it up till it's trying to lift
the whole thing off the ground. It's only a 2" square tube axle with
a 19' V8 boat on the trailer. 2" square axles can be used up to
3500lbs. The axle between the springs normally doesn't have any
significant load. The load is all on the last 4" from the springs to
the spindle.

I'm doing this because I'm thinking that over the 20 yeasr of it's
life it has slowly sagged in the other direction. Now I'm trying to
make it sag back the other way but hopefully a bit faster since I'm
putting a lot more stress on it.
