Autopilot for Tiller-Steered 22,000lb Displacement Yacht

I have been looking at the specs for tiller auto-pilot rams -- ie Raymarine -- they seem to be rated for up to boats of about 15,000lb displacement.

I'm _cautiously_ thinking about changing my 22,000lb displacement Union 36 to tiller steering (from Edson worm steer). So a tiller pilot would not be appropriate, given the displacement of my boat.

Next option would be a below deck linear drive.

However, the Raymarine website says their below deck linear drives are 'for mechanically steered boats' -- by which I assume they mean wheel-steering (tiller steering is not 'mechanical')

Can anyone think of a reason why I could not fit a Raymarine below deck linear ram drive directly attached to the rudder post (via short tiller) -- in conjunction with, say, the Raymarine ST6001 'head' and matched core pack?

I'm thinking that -- when such an autopilot system is steering the boat -- the tiller would need to be up, rather than (potentially) sweeping around the cockpit.

Anyone seen such a system in operation?

Unless you're somehow changing the rudder post itself, I don't see where it would matter if it's attached to a wheel or a tiller, if the linear drive mounts directly to the post for a wheel steered boat.

Correct...you simply attach the ram to the quadrant....and mechanical steering in this case simply means "not hydraulically steered".... i.e. tiller or wheel steered by hand/cables/gears. You can buy quadrants and fit them to your rudder post if needed.
I would however suggest something other than the worm gear RayMarine unit...prone to failure. Prefer the Simrad approach myself after going through 2 raymarine worm gears in my 25,000 lb last boat.
You need something like this:

The hydraulic/ram unit will attach to your quadrant and the main issue for most installations is finding or building a stable platform to mount the ram on so that it can drive the adjacent quadrant from the right distance/angle. This would apply to ANY brand under-deck pilot.
