The Edson bearing comes with an aluminum sleeve. If that is removed the rudder shaft should be 101.6mm (4 inches). The Jefa bearing would have a sleeve with an I.D. of 101.6mm, O.D. of 108mm. This would match the self aligning bearing that has an ID of 108mm and an OD of 152.16mm. The Jefa bearing is self-aligning but will need a fiberglass tube to be glassed into the boat to extend up to the waterline and then a gaiter is attached to keep water out. Some photographs of a Jefa bearing and gaiter installed on hull 266 are in this post.
A drawing of the Jefa bearing is attached.
