You can drop the rudder by attaching a rope to the cross bar in the top of the rudder shaft. If I was doing it I would probably use a wire rope and a short section of pipe over the rope to shield it from being cut. My stern sits high enough that the rudder post is never in the water while sitting idle.
My rudder does not appear to have been re-machined. It does have a keyway the entire length of the shaft. Same situation though with dropping the rudder. It can be done in the water. They are nearly neutrally buoyant so with a man in the water lower the rudder with the previously described rope. Once lowered below the hull. A second rope can be attached and a crane or davit can be used to lift the rudder from the water.

If you perform the install with the boat in the water you'll have to use something like a pipe cutter since the rudder shaft will be in the way. I have heard of being able to attach a strong rope to the rudder "bail" and lowering the rudder out of, or nearly out of, the boat which would facilitate making the required cuts also. >>> >>> I would consider doing all of the glass work and framing now and when the boat is hauled finish the project by removing the rudder, making the required cuts and then reinstalling the rudder. >>> >>> Josh >>> >>> On Jul 7, 2015 5:04 PM, "Gary Russell via CnC-List" < cnc-list@cnc-list.com> wrote: >>>> >>>> Hi Josh, >>>> Is the rudder shaft exposed under the deck (I haven't crawled down there yet), where you can clamp the bronze arm? >>>> Gary >>>> >>>> ~~~~~~~_/)~~~~~~ >>>> >>>> >>>> On Tue, Jul 7, 2015 at 12:35 PM, Josh Muckley via CnC-List < cnc-list@cnc-list.com> wrote: >>>>> >>>>> Sea Hawk came with a simrad package already installed. There is a shelf which appears to be 3/4" plywood encapsulated and glassed to the hull under the stbd propane locker. The hydraulic piston is mounted to the shelf and drives a bronze arm attached to the rudder shaft. The feedback positionner is mounted to an additional shelf on the port side of the rudder sleeve and the linkage attaches to the same bronze arm. Right now all I have are pictures of the bronze arm. The arm is a standard piece which can be bought on defender. >>>>> >>>>> https://drive.google.com/folder/d/0B8pEh5lnvP1yQWIyanRiTzBKRlk/edit >>>>> >>>>> Josh Muckley >>>>> S/V Sea Hash >>>>> 1989 C&C 37+ >>>>> Solomons, MD >>>>> >>>>> I just bought a 37 Plus and want to install a below deck autopilot.
