I am running an OFS4 15.25 x 15 on our 225 Tournament, Yamaha F225. I feel it is a good match for the hull. It doesn't give the best top end (5800rpm 39mph, bottom paint...) but I can stay on plane in the slop at 20-21mph and cruise comfortablly from 26mph (4200rpm) to 32mph (4600rpm). Hole shot is also great. I had a load of 5 adults and 4 kids on the boat a couple of weeks ago and the setup did not leave me wishing for the F250.
