I heard 225 Optis should run w/ 24 4B bravos 66-67. With a paid of labbed 3 blades you can get 70 but you will hurt the mid range. If you take the time to dial it in you can get more. I just put a pair Mercury Revolutions 4 blades on my 32 today and I increased the top end by 4mph and the mid range by 2mph. I can still get another 300RPM by labbing them.
There is and 04 in NY for sale on boattraderonline.com. Really good price.
