I am in need of a rudder packing nut and 2 jam nuts for a 41 Roamer Regal. The packing nut has the Chris Craft name on it with two different numbers. The numbers are 394 and 470. The shaft size is 1 3/8 inch in the area of the packing. The packing nut hex measures 2 3/4 inch.
Have you looked in the Library Links section???
