Yes it's a 17" pitch and it's the largest diameter available and it has a large blade area, it's a Turning Point brand. I think this is the one in the link below I bought with the Honda hub from WM when they had them on sale (of course). More in to steady performance when the boat is loaded and fuel mileage. Not worried about WOT speed. It was actually the one Josh Stoner used in his first 23'er with a 250 Tohatsu and it was his recommendation that I tried it on my SC. Much better than either the 17 or 19 Honda props. Good luck.
