    Update, my son cracked the drive wheel while tightening the bolts Rudy is going to look to see if he has one in the morning , 5.15 hr road trip if he does . There is one with exact part number and exact patent number for 105 on eBay, but the shaft hole is to small.

    I have been following this thread as it reminds me that things on my boat could be worse. I feel for you, but would love to see some some PICTURES!

    Robert,

    I replaced the rudder on my ‘86 ODay 31 about 5 years ago. I needed another person outside to help me while I worked on the inside. The original was coming apart and had obviously been bad for a long time. The Maine surveyor and my insurance company insisted I replace it.

    I had the boat hauled out and placed on a steel cradle. The bottom of the keel was about a foot off the ground. I disconnected the steering cables from the quadrant. Next I thoroughly soaked all bolts with a good penetrating oil (Kroil is best but may be hard to find). There is a large bolt that passes through the quadrant halves and the rudder stock. I dug a 2’ Hole below the rudder and temporarily supported it before removing the stock shear bolt and quadrant halves.

    I bought a new rudder from Ruddercraft made of all stainless steel covered by HDPE. It cost me $2K plus shipping. They have the plans for it. It is probably the same for a 30 footer but send your old one for them to check to be sure.
    The original rudder was made by Foss Foam and had a stainless steel stock made from 2” schedule 40 pipe but carbon steel webbing covered by gel-covered haves fiberglassed together( not a very sustainable design).

    The only issue was that new one was made from schedule 80 pipe so my emergency tiller had to be replaced. They made a new one for me that fit the thicker pipe. They have plans for that too. The new rudder is made much better than the original and because it is solid HDPE (high density polyethylene) cast over all stainless steel welded web and stock, it cannot get “waterlogged” and break down.
    Just be careful to get the hard plastic ring bushing on the stock correctly before reinstalling the quadrant. If it’s not in the right position the stock can’t go in. This bushing bears the weight of the rudder and resists wear from turning.

    The stock penetrates the boat through a fiberglass tube that’s about 2 3/4” in diameter from the hull up to the opening in the cockpit seat . It is only open where the bushing and quadrant are located well above the waterline.

    It’s likely that this tube was over stressed and cracked when the rudder stock was bent. With the rudder removed, I don’t think it would be difficult to somehow plug the bottom of the tube with a 2” rubber pipe plug from a plumbing supply then fill the tube and search for any leaks below the quadrant. If that doesn’t work, plug the top also, wrap a pipe repair clamp over the quadrant opening then put some air pressure and check with a 50/50 dish detergent to water solution. Bubbles will form at the leak points. The repair then would be cleaning the area with acetone then fiberglass wrap and West system epoxy and hardener.

    Sorry but it’s obvious that I responded too late without reading the other comments. Best of luck with the repairs!

    Thanks for your response, someone who did the same repair with almost the boat is valuable info. I don't under the stock that your talking about. There would be no room for anybearing or bushing around the steering quadrant and rudder post ?

    The used rudder was actually in pretty good shape , better then the photos, when does that ever happen lol. The rudder post on the eBay rudder was a,tiny bit bigger , this caused the quadrant to crack when my son was tightening it. So a machine shop welded it, now I need to fiberglass in the upper rudder tube that the boatyard messed up .

    The million dollar question is this. When looking at the interesting diagram on Edsons website which has 2600 I believe boats . The diagram for the O'day 28 /30 says may need a stuffing box bearing , indicating shoved in the rudder tube below the steering quadrant. The helpful poster who replaced his 31 ft O'day rudder states that the bottom rudder tube is well above the waterline and stops at the steering quadrant .Thus indicating no issues with water intrusion and no mention of a bearing in the lower rudder tube to prevent water intrusion. Tomorrow morning I am glassing in the upper rudder tube, which is light duty and just seems to help keep the rudder tube lined up . If there is some type of stuffing bearing needed then once I glass upper tube , the rudder would have to come out to install it . Anyone who has knowledge of this bearing being or not being there please chime in because this boat is hopefully finally going in the water this wknd. The whole assembly seems pretty simple now , not scarey like in the beginning except for that nice but confusing diagram on the Edson site. Kind of like getting married and the preacher says I now pronounce you man and wife and she may or may not have sex with you, ie your boat may or may not sink .
