Re: Year of Manufacture and Diagrams Needed

The spring is flat and goes from the top drive shaft to the lower stub. At the end it looks like a tang.
The brass cone provides the detent for the gearshift. It rides against a flat shaped cam with indents in it.
The shift works by the cam pushing on the pin in the center of the prop shaft.
Proper operation of the shift requires a gearcase gasket of original thickness so sealer alone will not work well.
