Not any harder, just more fun
Quicker,
Not any harder to drive, just a lot quicker. It's the most fun, cruising about 3000-3500 and then stabbing it. The whole boat torques and the motor seems to turn up instantly.
It's no drag boat, but it does pretty good for a big ol' family cruiser. I'm sure if I were to pull out all of the family crap and increase the trim to 24V it would surprise a lot of people.
