TH Marine Jackplate Question

[gizzardshad]

Can anyone tell me exactly the purpose of this bolt? After running down the lake a few miles this past weekend in some fairly rough water I noticed the bolt in this position after pulling the boat out. I assume it should be flush with a lock nut on the bottom but the nut is gone. I can't really tell the purpose of the bolt however. Am I good to buy a nut and simply tighten it up or has anything moved?

That's the bolt that raises or lowers the jackplate

It has several nuts on it
I took this picture during my transducer install and it shows the nuts and fittings at the bottom of the boat

The bolts on the side of the jack plate lock it in place once you adjust the height
So your proper height should still be there

So I have zero nuts on mine.. Not sure how long it has been that way. Anyone know the best way to get these replaced...contact TH Marine?

I would say Contact TH Marine

If that dont work you can get stainless nuts and washers
use my picture to figure out what you need
