Hi Mark!
Sorry for the delay in responding to your PM (and hence, this post), I've been having a monstrous year so-far, trying to prep and sell our property for an eventual post retirement downsize.
For the long, and the short of it, my Baystar kluge was overall - successful, and cheap enough to avoid taking out a second mortgage (as some might imply). I have to thank Mastreb for the initial sale notification clincher, that got me going). Funny how we don't exactly apply the same cost/performance rules when considering the application of much more expensive powerplants to our hulls - but I suppose it's all relative to what we hope to end up with!
Having said that, I'm going to step back a little and give you a few negatives:
Just substituting a hydraulic for a purely mechanical set-up won't eliminate all the play you're commenting on. There are quite a few components in the lineup that will add up to a cumulative wheel turning before the rudders grab water, and eliminating these (which I haven't fully done yet) should be your first line of attack. On an M (mine) those would be:
Port and starboard link arm attachments.
Rudder hinge bolt spacing/tightness.
Rudder bracket hinges.
Helm attachment to link arm.
Helm.
If you search through the many posts, on this site, dealing with this subject, you will surely find that the primary culprit is the helm gearing slop, in most cases and as said, replacing that, or fixing it, is the cheaper option. I went hydraulic to cover two factors: Taking out at least fifty percent of the play (that belonged to the helm), and giving me an eventual avenue into a Raymarine X10 hydraulic auto-helm (apologies to Victor here!)
As for the remaining 'slop' it becomes somewhat of a quest for the Holy Grail. I haven't done it all yet, and what I've got left seems to bug me even more - but now at least I know where I need to go to finish with it.
I have to say that my approach is more suited to an M than an X because I didn't want to use the engine well, and separate the two systems from each other. You can definitely feel the difference in effort through hydraulic back pressure when both are connected together (Hence - multiple previous BWY disconnect postings also). I don't think you can do the same with your configuration....
One thing a mechanical steering system can do is provide a modicum of rudder feedback for that enjoyable helm 'feel'. Nothing like a tiller, mind you, but possible nonetheless. As I've indicated above, I'm an inveterate tinkerer, and may eventually try to remove the check valves from my Baystar helm to restore some of that. As it operates now (without powered autohelm) it's 'point, load and lock'.
I will be doing a MOD review sometime soon and spell out a few revised linkage tweaks and angle adjustments - but first 'The House!'.
