Teleflex steering adjustment

Hi,
I have just fitted a 1963 Evinrude 18hp to my boat,the steering works fine but the amount of travel left and right is unequal.The steering rod at the engine end has a large nylon nut on it
which is on the rod,and I think is to adjust the travel.I can't see a locknut on it.
Can I just wind the nut without holding the shaft to stop it turning?
The fixing plate that carries the rod is clamped onto the splash back well,and has a nylon
swivelling ball joint that the rod passes through.

 

The adjustment should be done at the engine. With the cable in its middle position, the hole on the engine bracket should bolt when the engine is also in the middle position.

 

Hi Gonzo,
So what is the big nut and the thread for on the steering rod?
The throttle and gear cables can be adjusted at the engine,which I have done.

 

Maybe I am thinking of the nut on the steering tube. Is this a long threaded pipe on a swivel ball? That has an adjustment. (like this splashwell mount: http://www.jamestowndistributors.com/userportal/document.do?docId=711

 

That's it exactly Gonzo,the splashwell mount.
My original query was,is there a locknut on the shaft,or is the nut in the picture just used to wind the shaft in and out with nothing locking the shaft.
The connection to the engine would have to be undone of course to allow the shaft to turn when adjusted.
I suppose once the adjustment has been made and the shaft reconnected to the engine,that in itself locks the adjustment.
The link you sent has certainly helped put me in the picture many thanks.

I think you got the idea.
