Mark, I would think that because of the X's very different configuration, and the benefits that accrue from disconnecting the engine when sailing, I would personally choose the cylinder connection that substituted for the mechanical pushrod linkage, instead of the engine well solution.
I still maintain that you might be surprised at the improvement you could obtain by eliminating the simple swivel bolt linkages with zero play bushings, such as Heim (aircraft type) joints. On my M, besides the original rack and pinion play, that was eliminated with the Baystar helm and cylinder, the largest overall area of take-up play was negated by shimming, and tightening, the rudder pivot sleeves. My first fix tried to use CD's (DVD's actually) directly on each side of the blade, to dial out the gaps before snugging down the pivot bolts. I took a generous grant from 'Seahouse' and went to a fitted cut-out polyethylene sheet instead. that took a much higher bolting load which completely eliminated all the play in this fixture, yet still let the rudders raise and lower smoothly. Try that first before you shell out the bigger boat bucks for the fancy hydraulics!
The best forensics to do is to rigidly clam both blades straight, and together, then with a friend's assistance continually rocking the wheel side-to-side, feel every connection to ascertain where your worst 'gremlins' are.

Other posts here have beautifully illustrated the need to balance the boat with proper sail handling, so that the rudders, under most points of sail, are basically pointing straight, fore and aft, instead of ploughing through the water sideways, and reducing speed. Also, miss-alignment of either rudder to the other, will give you the feel of having too much play in your particular set-up.
It's like a dog chasing its tail...... it never ends!

Hey Crikey! :D

Glad it worked for you.

For others interested, the mod Crikey refers to is described here...

Do you have a source for the heim ball joints?
That part of the steering isn't too bad but it is sloppy.

The cable part has way too much however. I can move the wheel
at least 60 degrees with no movement at all at the end of thee cable. That part
explains a lot of the mess.

The center mount cylinder I was going to mount to the center of the steering bar not to the
engine. I think I have a way to disconnect the engine but haven't got that completed yet. That will be
after everything is working :-)

Sea house thanks for you mod post. Looks like a great fix! Do you have a source for the ldpe

Mark, here is the link I used for my 'Heim' joints (called spherical rod ends in their site):
http://www.midwestcontrol.com/part_family.php?id=8
If you check through the site you will find the same kind of quick release connectors as used on the BWY engine disconnect. Those might come in handy for modding your particular model.

I would advise you look more closely at your rack and pinion helm in the pedestal. That much play might be adjusted out with suitable shims or re-machining something inside. Something ain't right! :o

Looks like the pinion on the wheel side has a bearing bad. If I can get the right parts from teleflex
I think all the will be good. The cable system doesn't seem that great especially
when I have been using hydraulic for ever except on small boats. Thanks for the link too. Now
I need to find the shim plastic and maybe it will be happy!

Hey Mark! :D

I used LDPE (Low Density Poly Ethylene) simply because I already had a left-over piece on hand. HDPE, UHMW, or any number of other slippery-surfaced plastics will do the same job (some materials are even better-suited for this purpose, like bearing plastics, but cost more if you’re buying it).

Get UV-stabilized product if you have a choice, but I don’t think it’s essential for this purpose. It’s 1/16” poly sheet that you want to ask for, if you live near a city that has a plastic manufacturer, they will recommend something that they have on hand – sometimes you will have to buy a 2’ X 4’ sheet.

I did a quick search online, you might try the same, there are lots of sellers, any of these should work…

(I think the thickness tolerance is missing a zero and should read +0.0035")

Good luck!- Brian. :wink:

It takes longer to research and get the parts than it does to make it all happen! Thanks for the links.
I sure do appreciate the help!
