I think you went with the Yamaha F225 right? It's pretty common knowledge that both the F200 and F225 are overated in the HP department. For comparison sake on my boat the differance between the new F150 motor and the older F200 is exactly 1-mph on the top end otherwise the F150 performs better across the board.
It seems Yamaha followed Suzuki's lead with the new F150 motors. The big Suzukis are supposedly giving any 2-stroke whether it be HPDI tech or not a run for their money.
I forget what size boat did you have 23'? Maybe you can play with props and tabs to get better performance. It will be tough to get anywhere near the performance of the twin 150s though.
The 225hp will shine should you ever decide to sell this boat
