Looking for recommendations I want to fit a new cutlass bearing to my old walker H28
It is not about the "brand", it is about the material it is made of.
Being as how you want to go traditional, lignum vitae would be fitting, but IF you can find it, the cost might be more than you have spent on the yacht so far.
If you are going to replace your existing I suggest getting the old one out first and see how much damage the extraction causes to where it was bonded.
Once you have cleaned up the damage and made the aperture into an as near as possible a cylindrical hole, get somebody to turn up a bush from Delrin or similar. It needs to measure 5 thou less on the O.D. than the hole it is going into so that it can be glued in with epoxy glue. The I.D. needs to have grooves in it to allow water lubrication and maybe 3 to 5 thou clearance on the shaft.
Before extracting the old stern bearing you should fit up the engine on the old shaft and bearing as accurately as possible and give it a run to make sure bearing and shaft replacement are really necessary. If it is necessary, use the engine position as a datum point to which the new shaft and bearing will be fitted to.
Ask yourself the question and answer it honestly "Do I really need to replace the stern bearing??"
