A 150hp Honda would be no problem - right Reelapeelin?!
Here is a test you could do-
Take a 200 lb (very brave) man and have him sit directly on top of your 150 2 stroke while you do a hole-shot out of the water and venture out into some swells. With this temp modification technically it should perform about the same as the heavier 225 as far as porposing goes.
I know its not a realistic test that that's about what it would be like.
I'm going to have to agree with Pink Jeep.
