A friend in our boat club was given a bronze 3 blade Columbian prop for his ’60 Johnson 40hp. The hub was longer and thinner than the standard big twin / 40 versions and didn’t fit. I thought it might have been an early V4 prop, but wondered if anyone here can indentify please. The markings around the hub are Columbian_F_L6DB.
hi, in my 1964 Columbian prop catalog shows new lite line props, Gale 60 10×11 3 blade L6DB no F. Note: small hub need prop nut #309947, drive pin # 309954,cotter pin #309955, thrust washer #304576.
