Not quite the same boat, but I had a 190 single console with a 150 EFI back in the 150 max days. It was outstanding. No GPS then, but it showed 63 on the speedo. So, prolly 55-57 actual. Most capable rough water boat I've ever ran. Perfectly balanced and excellent bow control when it got rough. Even better than the 202's and 203's I've had. Ran a 23M Yammie prop on it.
