seahorse 4 prop

[bass hound 02]

Well I finally got the registration back for my boat and we went to try it out it ran pretty good but I think I need to do a little more work on the carb... the reason I am posting this is that I made a 2 blade prop out of a 3, The prop is a 2 part plastic with a rubber bushing in between. I have a 1974 4r74r 4hp johnson does anyone sell a aftermarket prop for this engine? could i get a steel or aluminum prop? any help would be great
Thanks Chad,
