Re: Stus-List Rudder axial play
If these links work, here are a few photos of the washer at the top of our
rudder. This is the washer between the blade and the hull (rudder tube
bottom).

Re: Stus-List Rudder axial play
Thanks for the responses, gentlemen. I’ll pull the radial quadrant to check the
bearings, then, when I get hauled, I’ll look for the spacer bushing. I have a
piece of Delrin I can cut a new bushing from. I’ll certainly be happier when
the steering and rudder are all checked out.

Re: Stus-List Rudder axial play
In the case of Kaylarah ('90 C&C 37+) which should be the same design, the
rudder hangs on two ball bearings on a transverse shaft that sit on top of
a round metal bearing plate on top of the deck. The only thing that
restricts upward motion is a Delrin shim washer that sits between the top
of the rudder and the bottom rudder bearing.

Re: Stus-List Rudder axial play
Ours is set up like Chuck's, thick derelin washer at the bottom between the blade and hull, and rollers on an axle that passes through the rudder tube, rolling on a metal disk at the top, all hidden from view under the Radial Drive Wheel (quadrant). One possibility is your rollers are missing from the little axle Radial Drive Wheel? That would introduce an extra 1/2" or so of play. >From the factory, the rudder tube is continuous, from the hull to the deck so the distance between them is fixed. Some boats have had the rudder tube cut to insert an Autopilot Tiller Arm. In some cases that could introduce a change in the length of the rudder tube dimension as it now has a gap. Has your rudder tube been cut for an Autopilot Tiller Arm? Just a thought, Ken H.

Re: Stus-List Rudder axial play
Our rudder has a 3/4" thick delrin washer that sits on the rudder shaft above the blade and under the hull. The weight of the rudder is supported by a set of rollers on a shaft that goes through the rudder shaft above the deck. There is also a metal wearing ring that the rollers ride on. I think 1/4" or play might be OK, but 3/4" seems extreme and the rudder blade should not be able to clunk, or strike the hull, as it could penetrate it and cause a sinking. Also, excessive up and down movement could unreeve the cables from the quadrant and cause a loss of steering. Ken Heaton and Josh Muckley will have better info, but I'm thinking you may need to add a delrin washer.

Stus-List Rudder axial play
Hello All, The rudder on my C&C 37/40 was clunking while running before a following sea. I removed the pedestal and cables to replace my idler plate and when I grabbed the radial quadrant atop the rudder post to check for play I found quite a bit (3/4"or so) of axial play (up and down). My question is; how is the rudder located in the axial plane? Do the upper and lower bushings act as thrust bushings as well? I've looked at the rudder drawings provided by Ken Heaton but can't tell if the lower bushing is the one that sets the end play in the rudder shaft. The boat will be out of the water soon so that will be my big chance to fix this. Alan Liles SV Elendil, C&C 37/40 Vancouver, BC ___ Thanks everyone for supporting this list with your contributions.
