15 or 17 Pitch stainless prop for Yamaha 150 Wanted

[Rayvon]

I have a 15 Pitch aluminum prop on the new ( to me) boat that seems to work fine but I would like to keep it as a spare and put a stainless 15 or 17 pitch on.Diameter can vary from 13 3/4 to 15 1/2 ,I think. Motor is a 1994 2 stroke 150 H.P. I'm not comfortable running without a spare on board. Anybody have an extra one not being used? They are pricey new so looking used.Thanks,Ray
