I want to adjust my jackplate some, I just want to confirm it isnt much more than marking the original position, loosening the six bolts from the inside of the jackplate(brass bolts) and tightening or loosening the center adjusting bolt. Also, is their a recommended torque spec when tightening.
Thanks in advance
Is it a Z-lock? Good luck.

z-lock?
loosen the nuts inside the plate a few turns
loosen the bolts
adjust up/down, you may have to wiggle the whole motor, a little, or a LOT, to get the plate to slide down, if that's the direction you want to go
tighten the bolts, yes the bolts are threaded into the inside plate section
tighten the nuts.
test
do again, and again, and again, or get a hydraulic plate and do it once. Then experiment now and then.

As txbass1 said good luck!
A couple of things I learned on the z-lock. Yes there are brass nuts on the inside, however the bolts are actually threaded into the inner portion of the jackplate. I learned that and then confirmed it a while back when a bolt broke.
My recommendation is to loosen the nuts and then the bolts to allow it to move.
On my 721, I put a block of wood under the skeg and tilted down on it to take a bit of weight off of the plate, then I was able adjust it. Then tighten the bolts, followed by the nuts.
As to torque specs, I found nothing.

I broke two adjusting bolts trying to dial mine in after I bought it and finally gave up. Bought a Bob's and the Z-lock is sitting in the floor of my storage two years later. Can't bring myself to sell it to anyone with a clear conscience.

thanks for all of the input. I think i'll leave it alone till the end of the season incase something goes wrong.
Shoot me a pm with your addy and I'll mail you the top adjusting bolt #3 that was replaced by THM that I never installed. Least I can do. It took em a week or more to replace the first two- maybe I can save you some downtime and frustration.
