I'm parting out a Goodyear Seabee and I'm trying to remove the prop and I'm puzzled on how to remove it off the prop shaft.I removed the lower end and have the prop shaft.gear.housing,prop as one unit and It seems that the prop is pinned to the shaft.There are 2 holes on the prop housing and I can't see what might be holding the prop.I tried a gear puller and it feels like it's pinned in.Are the holes for access to a screw or pin?The prop nut is missing.Any help would be great.
