Those of you with any experience in pontoon boating, could you tell me if you can water ski behind them? I think I recall seeing people skiing behind them...

If so do you need the giant V8 gas guzzler or can this be done with a 135 HP Merc cruiser?
I want the party boat and my wife wants to be able to water ski.
I'm looking at a 24 ft with 135 HP that is a good price!
Is there any basic rules (formula) on pontoon boats performance in regard to length vs horsepower = water ski capable????
Any body have any experience with this?
Thanks
Bob
