Prior to dropping my rudder, I had been concerned by what I considered a bit too much vibration at certain angles of heel and speed, but others (more experienced) have told me not to be too worried. I was grateful that S2 had the flange bearings, but honestly it seems that a better substitute is out there to fit over the 1 1/2" stainless rudder stock (the washers can be had at most hardware stores). I consider myself lucky that my rudder stock is true and that the fiberglass tube in which it rests showed no signs of unusual wear.

One thing that did puzzle me was that the tube was not reinforced/tabbed in at the deck opening (it was obviously heavily reinforced at the bottom). I chose to do some grinding and tabbed in the tube to the underside of the deck. If one was concerned about excess wear in the tube itself, I would recommend the West System approach where you selectively drill holes and inject epoxy with the rudder stock in place (and waxed). The method is outlined in the boat repair flyer or online.

I noticed those bearings look a little ragged on mine - replacing is probably warranted;

once I get it out I'll check the tube integrity as well - I haven't seen any problems with that, but it's hard to inspect thoroughly.

Thanks for all the input... an amazing wealth of knowledge here...

S2 owners needing the nylon rudder bearing/busing can find them at Applied Industrial Technologies (Cleveland HQ, but many locations nationwide). The bearing is made by Thompson or Dohaner are called Thompson Nyliner. try Nyliner Bearings Many sizes up to 1.5 inch. S2 8.5 takes a 1.5 inch. cost was about $6.00 each.
