Mix 'n Match Newer Parts to Save Old Autohelm ?

[dergon]

Hi all -
Our 1980's version Autohelm 4000 finally died. The wheel pilot unit has a plastic sproket that is ground to pulp....dead dead dead.
I was trying to find a replacement wheel pilot seeing as the control unit is just fine.
Closest I can find is an Autohelm ST4000 MKII wheel drive only on ebay.
Could I use this wheel drive and just wire it in to the existing ancient Autohelm 4000?
Or do I have to bite the bullet and purchase a whole new autohelm?
Thanks,
dergon

Yes, you can use a mark II. The sprockets are sometimes on ebay.

you can even mix and match parts from the older 3,000s

The repeater control head unit for my Autohelm 6000 that is in my cockpit died. Manufacturer response was buy a whole new autopilot system . The autopilot unit still works fine ,looking to purchase a good used control unit for my Autopilot 6000 . I have been watching EBay ,no luck yet. Does anybody know if any other unit would be compatible ? The manufacturer says no.

I have a full 6000 that I just pulled from my boat. Probably won't separate (at first at least) . IM me if interested.
