The Yamaha Saltwater Series II 15.25 x 19 are the preferred props for those engines and hull. I ran those props on my F225's and I'm pretty sure most of the guys on here did as well.
I have a 2004 w/ the notorious F225 motors. I bought it with 160 hrs of her and 17 pitch props, when trimmed, the revs were too high, so I went the aforementioned 19 pitch props, which are just right.
