I had a 1998 H-56 with a 1998 Mariner 135. With the front storage crammed full & myself at 200 Lb. & a partner at 325 Lb. & a half tank (12 gallons) would do 59 gps with a prop that wasn't in very good shape. Xpress hyper lift hull series boats are by far the best performing aluminium boat on the market when it comes to speed & performance. The one & only down fall I had period was drifting in the wind. I also have had a couple older Lowes & not knocking them in any way, but If I were going back to aluminium again it would definitley be Xpress. Unless of course I couldn't get it in my garage. lol
