Hi Jere.
You put the boat on land, and lift it high in a crane or dig a hole under the rudder for extra space. You remove the tiller head, while the rudder is supported from below, and then lower the rudder. If you only want to change the rubber hose, you don't need the extra space below, but if you want to change the bushings as well, the rudder must come all out. I did so while the boat was hanging in a crane from the truck, that put it on land, and then the reverse when the boat was put tinto the water.
Jesper.
