This is a factory Stainless steel prop for a Johnson or Evinrude 80, 90, or 115 hp engines. This is a 13"×17" prop and also will come with all the mounting hardware. The blades are in perfect condition and all you need is to paint it. These were called SST props back in the day because they had a Teflon coating for improved slippage through the water. This is a 700.00 prop new so anyone looking for a high performance prop for cheap here you go..!!! See pics for size. Price is firm.
