Sorry for the slight hi-jack......

I have the opposite problem - the cams won't stay locked down. We replaced 1 of the plungers when it disintegrated this year, but the other is still the original (the old style with the loose ball). How do I determine if the repeated kick-up is due to worn cams, springs, plungers, or other parts?

ps. Old style non-adjustable rudder rake castings, rudders already re-drilled.

Thanks, Kris
