Well this part has raised its ugly head once again. Mine finally has completely broken. First the tab that held the shift cable retainer broke necessitating desperate measures with a batten. Then when I took it off it fell apart into four large pieces right at each of the countersunk screw holes.The tension from the countersunk screws must have cracked it over the years. The pictures were taken after I painstakingly Super Glued the entire thing back together.

I know that the cast aluminum replacement part is no longer available because the foundry burned down including the mold in 2009. I've seen the fixes from back in 2008 with epoxy, but I think mine is now beyond that. I've talked to a machine shop here in town and they are looking into hogging a suitable part out of a piece of aluminum billet. I will know later this week what they think.

How many others are now on the verge of a complete failure of this control head? Lack of availability of this part could be a real show stopper I would imagine. I understand that the YS pedestal was used in a number of boats other than Hunters so presumably there are lots of you out there. Any other solutions been tried (or purchased)?

By the way, a number of times people have asked how to keep the throttle control from backing down. Have tightened the little clamp down next to the engine that crushes the cable casing to the internal cable. Also used bungee cords and tennis balls stuffed into the space between the handle and speed pod. Well, upon inspection there is a little hole in the top of the control head over the throttle lever shaft. Inside is a bronze screw with a plastic tip that pushes against that shaft. Turn the screw a little increases friction to keep the lever in place. It has only taken me 27 years to find that adjustment. Now you know.

Hi Allen:

The condition of my Yacht Specialities "control head" when I bought my 1980 Hunter 36 was in one piece, but with noticeable stress cracks on the interior "tangs" on to which the morse cables assemblies are bolted and also which hold the control lever thru axles in position. Give me some time to think if I can possibly describe how I restored mine so that it will never break (ok maybe not never, but very unlikely) as yours did. But in summary, I bent stainless steel sheet metal in a manner that sheathed over the existing tangs. Drilled holes in the sheet metal in the right spots to accept the morse cable bolts and the control lever axles. Then I dammed up the center opening. Finally I filled the whole control head with west systems epoxy; essentially turning the thing into a solid puck. The epoxy sealed the stainless steel tang sheaths into the matrix. This was the first time I had ever worked with liquid epoxy and mixed too large an amount. Had some very anxious moments when the epoxy mixture began to overheat. Certainly next time I would fill up the space with several thinner layers. There were a few more elements to my process...and it was done five memory fading years ago. Let me know if you have interest in this repair concept and I can give more thought on how to describe. Obviously with my control head mounted, and the repair not visible, no photos! My repair was non destructive. Post #6 of this thread has a photo of how it looks now.

If ya take it to a shop that has a multi-axis CNC machine ya might be able to talk 'em into making one.. I think there is a potential market for probably over 100 of these .. so he could sell them at $250 each or so..

That could be done at a condiderable savings if the piece was optimized to minimize metal removal. In other words, what's the shape with the least amount of machining? The original being a casting, minimal metal use would be a driver in the design, but looked at from the other end (solid block, carve away anything that doesn't look like an elephant), it's possible that the simplest form is very simple indeed.

I wonder how Hermit Scott is doing and if he has access to a CNC machine?? I had to replace mine back in '95 when the part was still available in cast aluminum.. but it seems like it could be made from a piece of thick wall aluminum pipe and a flat plate welded to the top. The flat plate could have the appropriate brackets and holes installed..

Good suggestions. The machine shop does have the CNC equipment and I have talked to them about only removing what would be absolutely necessary for the function. Once I get my "prototype" from them, they will have the control program and should be able to replicate on demand. Maybe something that could be ordered through the HOW store?

Thanks for the offer Woody. Let's see how the machined one works out.

I have a Yacht Specialties head in stock that has Fig 329 embossed on the inside. So, it might be slightly different that yours. This one also has the bronze arm and shaft to the outside of the unit where the handle fits into the stainless base. Your picture just shows the bare white part. Anyway, this one is in good condition if you are interested in it. Contact me if you are interested or want some photos to confirm it will work for you. You can just send me a message via this site.
