Re: how much hp required?
What's the engine mounted on, that's got a lot to do with it? On a not too heavy boat you should be ok. Plus, much depends on the experience level of the skier. For instance when my son (who was already a decent skier) first decided to try wakeboarding I'd be at full throttle with my 90 HP Johnson trying to get him out of the water, felt like I was dragging around a huge anchor until he got up. Now that he has some experience under his belt he just pops right up with hardly any throttle at all.
