The hole is for access to this set screw that goes into the dimple in the crankshaft. I try to save pictures of the motors I repair so if I ever work on another it will show me what I did last time AND to be able to help others when and if I can. I don’t have all the answers but ask as many questions you may have so I didn’t waist all that time. I don’t have a manual but maybe this video will be of some help. https://youtu.be/K0veRUVxBjU

A "Boathouse Repair" is one that done without having tools or the skills to do it properly.
