I have a 1976 200 20hp mercury 4356766. I'm looking for the small machine screw that bolts half dollar size washer to the thumb screw. As you tighten the thumb screw this washer tightens to your transom. I need the little machine screw to this assembly. The entire thumb screw assembly part number is 74159A3. I have a parts catalog for this outboard, however, it does not show this screw. Where can I get one or a pair?
