Part number 305984 for the nut and 300345 for the lockwasher, from a dealer if you want to go that route. But there is nothing special about it. Just an ordinary thin "jam" nut. If it doesn't thread easilly onto your shaft, somebody has been hammering on the shaft.

Are you sure it is 5/8"? I thought it was 9/16" (7/8" hex) for the 35, and 5/8" for the 40hp. But could be mistaken. Anyway, the numbers I gave are for a 1959 35hp.
