Re: It never rains, it pours
I'm sure you're tried hitting it wirh a board across the leading edge of the blades. If the prop is still in fairly good shape you might try removing the spacer and putting the nut back on so there's a space. With the boat in the water, put it in reverse and power up. It may pull lose. Once it moves it should come off. You can do this with the boat still on the trailer and just backed down the ramp.
