Re: question...is this a left or a right hand propeller?
Based on the wear pattern, I agree with bondo. (I think). I forget which rotation is which.
I suspect that we are viewing this prop from the tailcone, not the back or engine side. Look at the root of the blades. That heavy triangular fillet is only present on the trailing edge. That would make it counterclockwise rotation.
And almost no one will write the pitch on the back surface of the blade
It looks similar in blade contour to the old OMC props.
