If old stye rudder castings, keep the metal rudder cams clean and lubricated with white lithium grease: this avoids breaking the aluminum rudder casting. If new style castings, keep the plastic cams in good condition by lubing then replacing them if they get bent or worn: This practice helps avoid rudder breakage.
