The tiller pilots are engaged by simply lifting the end of the linear drive
piston off the tiller pin. With my OEM linear drive, when not engaged on the
tiller pin, it swings out of the way to a storage clip on the stern rail.

BTW. The AH or ST wheel pilot, have internal belt drives with idler rollers
on a clutch lever. Not magnetic (couldn't/shouldn't have mag. around the
cockpit) or friction clutches in these. Trust me, I've had one apart for
voyage repairs in my last boat.
