Highly recommended not to go below the 225 hp. The other poster was correct, the Tournament 225 is a beefy fishing boat. In fact, the Tournament 225 gained more displacement over the past 10 years so 200 hp will not cut it. Please note that Grady is now pushing the F350 (a monster engine) on the 23 foot Gulf Stream in their showrooms, so you can expect the Tournament 225 to go up in hp soon, perhaps 275 or 300 hp especially if Grady incorporates an European transom.
