On the under side of the tiller arm there is a tension screw ... make sure it isn't too tight. It is simply a screw that threads through the casing of the tiller arm and friction rubs against the inside shaft. Corrosion or an incorrect adjustment may case it to be hard to turn. I always back mine off.... If I fall off the boat I don't want the bug ger coming bk looking for me at full throttle. Next would be to give the disassembled arm a good cleaning and greasing. It is very simple consisting of meshing sprockets hooked to a long rod.
