      The face of one tooth of the pinion in this 25 HP Johnson gearbox has damage (photos below). I think it might lead to gearbox failure. I would replace the pinion but can’t find an OMC number for just the pinion alone. Does anyone know a number/availability?
      Thank you.

        Not guaranteeing this, but it MIGHT be 375835 pinion and bearing assy.. Got the number from 1960 Gale 25hp parts book.

        EDIT: Just checked, several of them on e-bay at very reasonable price. Search for the part number 375835.

            I’ve run worse than that without any issues. If you find one cheap and want to change it, why not….
