How the %@#$ did I break that?

We have a saying in logging, 'give a logger two rocks in the morning, and by lunch he will have lost one and broke the other'!
So while sailing last weekend I felt some resistance on the wheel, heard a 'bang', and steering returned to normal. Turns out the Robertson Autohelm 200 had been accidently engaged and I had broken the 'dogbone?' connecting the hydraulic cylinder to the rudder stock - picture included I hope. It broke top left, right where the key goes in. Turns out there were 'voids' in the casting, which is, I suppose, why it broke there. The voids also made welding back together a real challenge.

So where would I find a new one? Stamped on it is TA 175 as best as I can tell. I realize Simard now handles the Robertson line, but it seems to me this part would not be supplied by them as it would not be a generic part but unique to virtually every boat model. Your help will be grearly appreciated.

Lousy picture, it broke top left. i have braised back together, but don't really trust it, and would like a new one and use this as spare.

tiller arm

I have a similar one on our boat with an old Robertson cylinder. That one looks like a Buck Algonquin. Edson also make one that is similar. Check with Fisherys Supply. They stock them.

Better tiller arm

I believe that you can get a generic, but way stronger, arm from Edson via Fisheries Supply. It will not break.
