Rudder
To Remove the Rudder
Loosen the wires on the quadrant. It's not necessary to undo completely. Chock under the rudder to stop it falling through. It's not necessary to excavate beneath the rudder, there is sufficient ground clearance. Remove collar, loosen quadrant. Remove keyway from under quadrant. (Use a metal chisel and a hammer and hit it very hard on the side of the keyway and the keyway will spring out. Do not be gentle!) Slide the rudder stock down through the bearings and remove. Refitting is the reverse of the above.
