Replacing top rudder board.

[Jfreeman1412]

Hey guys,
I am looking to replace the boards that my rudder shafts go through below deck. If my shafts are 1 inch, what size would I drill the hole for them to go through? I assume slightly bigger so the bearing/busching mount to keep the shaft straight and not have the shaft fit tight into the hole on the new board. Hope this makes sense and thanks for any help.

measure the OD of the bushing . you can go larger as its bolt on the support

I think I used a 2" hole saw. It doesn't need to be precise; it just needs to be big enough for the bushing to push through.
