Gentlemen,
Many years ago I had a Champion 16 hp. The blue prop is from that motor. The bronze prop looks to be similar but the shaft size is .625 rather than the .560 of the standard prop. The bronze
prop number imprinted on the hub is E13633. It also has 8X14 on the hub face but only measures 7 1/8 in dia. Any thoughts what it may be?
