No friction clutches or drag adjustments on any of the cables or
turning
spools? Maybe you could add one somewhere.

The cable is a single cable - push/pull. Not certain how I could
change
that in any way. That said, there is no slack in it at all, so I am
wondering why rudder feedback is even needed.

Larry,
look at fitting something like the Raymarine ST3000 wheel pilot. This
is
as
fitted to my motorsailer with push-pull steering, and does not need a
rudder
feedback. Also, the compass unit is in the control head, so only the
control
head and drive motor fitted, with belt drive to the steering wheel.
The ST4000 (I believe) requires a separate compass unit.
Go to the Raymarine website for some more information.
regards,
Philip.
Thanks, Philip,
Well, I asked Raymarine and they said the ST3000 would not work, nor
will
any unit they manufacture. He said that use of any autopilot with a
jet
boat requires something which sends the cpu the actual position of the
rudder (jet in my case). Also, it would be extremely difficult to
attach
a
motor to the wheel as there is no room.

Larry,
I hear what they say, but my ST3000 has no feedback or any way of knowing
where the rudder is when I engage the drive. It just uses the compass to
keep a heading and adjust steering to keep on course.
It is a pity it will not fit, but other than this, I don't think the
person
you spoke to actually knew the unit and its capability properly - if at
all.
regards,
Philip
I agree with both. I'm in a bind in that I am willing to spend the money,
but ONLY if I can make something that works. I wish there were a way to
connect a plain ordinary Sport Pilot to my wheel as it does not require
rudder feedback and it will fit. That way I could test and see how bad it
really is. Likewise the ST3000. The guy to whom I spoke seemed concerned
that a jet boat tends to respond very quickly to changes in the tube
(corresponds with a rudder). If there were a way to vary the sensitivity
of the unit, I might gamble.... Again, thanks for your help, Philip.

Larry,
have a read of page 59 of
http://www.raymarine.com/raymarine/S...3000_wheel.pdf
Maybe it will allow you to set it to either fast or slow response.
My motor-sailer has a very quick response to the wheel, and the ST3000 copes
perfectly - except when I am sailing with a quarter or following wind. But
then again, I have a problem steering with that angle of wind!!
regards, and I hope you find something that will work
Philip,
I'm beginning to think that I may have been given the wrong advice by
Raymarine. I realize, however, that it is doubtful that I can expect any
help from them. Perhaps either the 3000 or the Sport Pilot might be able
to be made to work. The Sport Pilot is a very easy install. The 3000 may
have different electronics. I'll have a closer look.
In my situation, even if the rudder gain is incorrect, I wouldn't care
since I principally want to be able to take my hands off the wheel to setup
the downriggers, so if the boat is just heading in the approximate
direction, that's ok.
Thanks for the help.
