Replacement Trailer Hub Grease Seal with Inner Diameter of 1.687 inch and Outer Diameter of 2.32

Question

Question:

Hello, I need to replace 2 seals on my boat trailer. It is hard to read, but I believe it is a National Seal #204017. This seal measures 2.32inch OD and the part of the axle where the seal rides measures at 1.687. Is the Redline seal #168233 a suitable replacement? Thank you
