Right Propeller?

I ordered a new propeller for my BHP20 from this Honda website. The new one is a bit larger than what was on mine. I rec. a 10X7 & 3/4. The old one
was a 9 1/4 X 10. The new fits, but I was wondering which one really should be on it.

Are they 3 or 4 blades? Are they aluminum or stainless steel?

Thanks--but how would the boat react to a 10 X 7 3/4? (on a jon boat)

The operating range for that motor is 5000-6000 rpm's(max horse power range) and you need a prop that will be within that rpm range at wide open throttle. A smaller pitch prop will turn more rpm's at wide open, be quicker plaining boat off and generally less top speed.
