[CA] [CA11] Autopilot clutch releasing

[daknecht]

I have been having trouble with the clutch arm releasing while in autopilot mode. The old FAQ related to the arm releasing says:
1) the vessel should be located dockside, on the mooring, or at anchor
2) on the back side of the drive loosen the belt tensioner's allen head locking bolt enough that the square belt tension knob may be rotated
3) tighten the square belt tension knob until the tension begins to be felt half way through the rotation of the clutch lever's range of motion
4) tighten the belt tensioner's allen head locking bolt

Does #3 mean tension is felt in the tension knob or tension is felt in the wheel movement?
