My 2015 X19 Coast Guard plate clearly shows the model as X19 and the hp rating as 150 HP. I bought the boat used, but I am assuming the HP rating is due to it being outfitted with a 140 Suzuki and Baystar hydraulic steering. Would Xpress rate a hull based on the installed steering system, or is there another reason that I am unaware of? I assumed all X19s were rated for 200 and didn't pay any attention to the rating plate until today.
