I think I'll live, but I may have to consult a doctor to be sure. When did everyone become allergic to gluten anyways? Growing up, I've never heard of that allergy, then all of a sudden, everybody has to stay away from it.

That's $2k - a set of custom machined Jefa roller bearings will cost you a lot less than that.

mine cost $600 - my stock is smaller than yours - but stil a long ways up to $2k

I was able to get a hand to move the rudder to see the movement at the top bearing. It looks like the movement is there. There is not much play at the bottom bearing. My current plan is to replace the top bearing first and see if that solves the problem. This doesn't require me having to have the yard re-lift the boat. If there is still too much movement, I'll do the bottom bearing.

You wouldn't have to move the boat to drop the rudder unless you are on pavement.....just dig a hole under the rudder and drop it down.....

Re: Question for the Pros: When to Replace Rudder Bearings?

Ooops, just saw your post about the yard.....geesh! Not getting any breaks here....

Friends of ours just did top and bottom bearings on their Saga 43...top bearing was 1800, bottom about 700.....they were lucky, they dug a hole and didn't have to relift.....not cheap these things!

Really? I didn't think they would be inexpensive. I doubt I would go with those though. That requires replacing the entire rudder tube, plus there's something to be said about plain simple bushings. While the roller bearings would be nice, I'm not a performance boat, and I worry about the longevity of the bearing. Although if they are easily replaceable, that's something that could be done in the water. My rudder stock enters the hull above the static waterline.

Does anybody know what kind of bronze is used for the bottom?

Wy would you replace the tube? I didn't. the rollerbearings come in a synthic material housing. Take the old bearings out - measure them on the outside (and inside and your stock).. The outside of the bearing housing as a set of grooves. fill the grooves with sikaflex and slide them up into the rudder tube.
Now slide your rudder stock up into the bearings (the hard part is getting the stock aligned and into the upper bearing)

The roller bearingsa re lubricated by salt water. If you are afraid of salt build-up, pour a bucket of fresh water down the rudder tube occasionally

When I spoke to Jefa (PYI) at the boat show, they said the roller bearings come pre-installed in a tube since that's easier and more reliable then enlarging the existing hole. There's no way a roller bearing would fit without doing that, as the bushing in there now is only maybe .190" thick. I would have to enlarge the ID of the tube, or reduce the OD of the stock.

I think such allergens became endemic after the advent of not drinking out of the garden hose and riding in the back of pickup trucks.... Sad demise...

I even pickled it up and carried it to my car all by myself.

Definitely a sad demise. Technically I'm part of the Millennial genereation, albeit barely, but I refuse to accept that. Calling me a Millennial is an insult of the highest degree. I consider myself the last of the "Walk it off" generation.

I had a quick look, but I still don't see how a roller bearing setup will work without major surgery. Click image for larger version
