Yes I have these ... To check to see if this is what you need ... Remove the cotter pin holding the cone prop nut in place ... Unscrew the nut ... Slide the prop off of the shaft ... The pin is located at the end ... Note always use shear pins and not nails, etc ... You want the shear material to snap/break not bend ... <'TK><
