I'm skeptical of the whole thing.

My Autohelm mounts in a HOLE that's drilled in a HORIZONTAL surface.
ANY horizontal surface.

The arm mounts on a ball end screw that is screwed into the tiller.

If it's the wrong height, as most are, use a block of wood. Most things
don't fit, exactly. But we adapt them.

I'm sorry, it could not possibly "not work" if it has a tiller.
