    My gudgeons are pretty worn and sloppy. next winter I am considering replacing. Looking at the top gudgeon it looks like one has to cut an access hole to get at the nuts and .... backing plate. I really do not like this idea. How about just drilling all the way through and using longer bolts on the inside ( outside?) of the cockpit? Of course using care not to crush the hull and cockpit together when tightening.

    I guess I will be able to get at the lower gudgeon without too much trouble.

    I would just install an inspection port. Or you need to sandwich something between the outer hall and the inner cockpit liner to avoid cracking the hull when tightening bolts that go thru both.... IMO more work and danger of leaks than the inspection port:

    Definitely inspection port.

    Well;

    I got this suggestion from the Capri 22 Facebook site.

    Patrick Gudat You don't need to drill. There should be a bronze plate that has been tapped for the screws. There are no nuts. I was able to replace my gudgeons without having any access to that area.if you loosen up the bolts, you can do a trick where you'll always have two of the three bolts and the plate and therefore won't ever lose the plate.

    Since I will have 6 months to work on the boat after I take her out in October, I'll try this first.

    I found this trick after doing a search on Gudgeon replacement Capri 22

    "First thing is you need two 1/4" all thread rods. Take out the outer two bolts and replace with the all thread then take out the inner bolts. Slide off the gudgeon caulk the new gudgeon and slide it on the all thread replace the inner bolts and remove the all thread replace the outer bolts, project over! "

    Of course this assumes the backing plate is threaded -- or the nuts are glassed on.

    Well; I had some difficulty removing the lower port side machine screw. So a big pair of vice grips did the trick. I busted the machine screw. Seems there was a locking nut on the other side of the plate. Well, that area is accessible through the storage compart on the starboard side of the Mk I's.
    The upper screws came out with some difficulty. Turns out there is a threaded plate behind my upper one also.

    When I called Catalina Direct to order parts and told the salesman that my boat had plates which were tapped and threaded he said "you are one of the lucky ones :) "


    For some reason the screws on the top gudgeon were shorter then the ones on the bottom gudgeon.
    Plate is from bottom gudgeon.





    The top plate is temporarily held in place with 2 machine screws with their heads cut off. Allows to slip the gudgeon off/on but holds plate in place.

    Now I am waiting for the new gudgeons from Catalina.

    So there were threaded plates top and bottom? Been wondering about this, since the gudgeon bolt kit that CD sells includes nuts and washers. Sounds like one of yours had a nut, but the others didn't? Seems odd. I am looking forward to the "rest of the story" as I am contemplating this on my boat also. I don't think I would fit down thru the hatch on deck, so might have to enlist some help from a thinner friend!

    Thanks for posting.

    When I called Catalina Direct and talked to the parts guy. He asked me if I needed any other hardware. I explained that I had backing plates with the holes tapped in. He said "you are one of the lucky ones". I do not know if that was a design improvement cut in after hull # ??? or it they just use what is on the shelf at times. My boat is S/N 427.

    I just purchased a 1/4-20 tap to clean out the threads. I guess there is a slight electrolysis between the stainless screws and brass plate.

    The top plate is still in and held by some screws with their heads cut off. I plan on cleaning those threads "in place".

    On the lower gudgeon there were locking nuts on both the starboard & port sides. I was able to get to the starboard side from the locker. I totally forgot about the port side ( brain freeze -- 68 years old) which is why I ended up breaking the machine screw, Anyway, it worked out for the better as I would not have been able to get at it otherwise.

    I am waiting for the new gudgeons.

    I know it's too late now, but has anyone tried tack welding some washers onto the old gudgeons to smaller the hole? Or, how about drilling them out and fitting some Delrin or bronze bushings?

    Not a CP-22, but my last boat had a transom-hung rudder with worn gudgeons too. One of my crew's father-in-law was a machinist, and he made some bushings out of Delrin. It worked great for as long as I owned the boat. That said, I think replacing the gudgeons is a better choice.

    YMMV,

    I again spoke with Catalina Direct. Seem that the threaded plates were cut in somewhere along the production. They did not keep track. But if your boats S/N is > 427 you should have the plates.'

    Buy the heavy duty rudder gudgeons from Catalina Direct. They are actually the rudder gudgeons from the C-250. They are much stronger, and have plastic bearings that are replaceable. I installed a set years ago and the rudder is still nice and tight. Order a spare set of inserts just in case you lose one. They are a plug and play using the same mounting bolt pattern.
