I've never been very impressed with the wakes that direct drives moombas put out. We've had about 1500 pounds plus 4 people and gear and the wake never got very good. It's a small rampy wake at best.
If your looking for a good Direct Drive wakeboat I'd look into mid 90's Mastercraft 205's and Sport Nautiques. Those boats have great hulls that will put out much better wakes.
I'm comparing these boats strictly by the wake I have no other issues with the direct drive moombas. They're alot of boat for the money.
