Vintage Outboard Motor Propeller 8" w/ Prop Nut 137 OMC? Johnson Evinrude

I'm not sure what make/model outboard this is for. It is stamped "137" on one of the blades. Shows some normal wear/aging but in overall good condition. Comes with the shown prop nut. Prop measures 8 inches in diameter. ~ New to Poshmark?
