I have owned many Prindles over the years and if the rudders and lock down mech. are adjusted properly they work just fine. What I have noticed in the past is that the springs do lose some strength after years of use and need to be replaced as well as the cams. If these are the originals they are between 16 and 17 years old. I also tighten the bolt which holds the rudder in the casting quite tight so the rudder will not drop from the raised position and then slowly back off the nut until it drops freely, this will take out most of the slop in the rudder casting.
