I have a new (used for 1 hour to test) powertech nrs3 13.25x16 Pitch SS prop.
I bought it for my Tohatsu 90hp TLDI engine but I need another size. It has 15 spline and wil probably fit other engines, but I am not 100% sure of that.
here is more info
I would like 250£ (272€) OBO exl shipping for the prop in original box.
