The Prindle rudder system works quite well when properly adjusted and maintained. The cam is adjustable and by moving it in or out either makes the rudder harder or easier to kick up. Make sure that the springs are free to move, do not over tighten the nut and bolt that holds them in place. Make sure that the knot at the end of the pull down line is small and will not rub the rudder casting when pulling the rudder down. Make sure that all the rollers and spacers in the system are in good shape and moving freely. I had Prindles for close to 20 years and once the system was adjusted I rarely had a problem.
