My friend has a 89 malibu sunsetter open bow. The wake is on the rampier side unlike the wall/lippy nautiques of that era. Definitely a nice boat! Here is a video of us riding behind it with a little less than 2k worth of weight in it. It could take more if the prop pitch was lower, i think he has something like a 13x12 4 blade.
We've also surfed it, kinda of a small surf wake but it wasnt slammed either.
