I have a New (Never Used or Fitted), 'Bolly' - Carbon Fibre Propeller. Dimensions - 21" x 10. This unit had been a spare for use on an OS Pegasus 4 Cyl 4 stroke (53 cc) that I had, but recently sold. It would also suite many other large engines of similar capacity. Priced to sell at $65.00. Pick up or Post @ $20.00.
