My favorite prop on the O.S. 52 for stroke is the APC 12.1/4 x 3 3/4 prop. it pulls like a tractor, and when you cut the throttle, it's like stepping on the brakes. Speedy it isn't, but then you are running a 4 stroke.

When I was first starting out. there was a guy on Ebay selling Zinter 12x6 wood props. Something like $0.50 each in dozon lots. I burnt my way through the first dozen then I tried the 12 1/4 x 3 3/4 and never went back.
