Hi, I've got an Inter17 with the original rudders -- I've got two questions about them.

1. Has anyone found it necessary to drop a rivet through the top of the rudder head casting to tighten up the little bit of slop in the tiller arm/casting connection?

2. Are the original rudders the same as the originals on the I18/20? Are the 2nd gen the same as the 2nd gen for the I18/20? Murray's shows the I17s as the same as the 570/580, but the nacra parts manual shows the I17s as the same as the 18/20.

Thanks!
