I recently purchased a new Xpress H51 with a 70hp Yamaha. This past weekend we launched it at Degray Lake and I was quite surprised at the way the boat handeled rough water. The ride was controlled and relatively stable thanks to the hull design. No rattles or squeaks during the ride. I'd have to say Xpress has done their homework! I shopped the competition and am satisfied I made the right choice. The Yamaha 70hp gives plenty of power for planeout and there's plenty of power for cruising.
