A friend of mine just purchased a new Duckworth with a Honda 225 on it. So far only a few hours on it--not yet broken in--but it is sweet. 50+ mph in a 21 foot boat from a quiet 4 stroke is nothing to sneeze at. And with Honda's history of reliability it's sure to be a great motor for years to come. About the only complaint I have is that I find the shape of the cowling kinda ugly--but I'm sure others would differ with me on that. Overall, I'd give it a big thumbs up if you're willing to pay the price. How much less is a Yamaha. . . ?

If you want further info, he'd probably be glad to talk to you about it, so email me and I'll put you in touch with him.
