My dad has an '88 Pachanga that he wants to sell. 78mph is dreaming that in that boat. I had his to just about 70mph but I would not want to go much faster then that. Has lots of room inside and it comfortable but does not have the best ride in rough water. A little heavy but can still be fun. If you want to talk to me on the phone about these boats pm me and let me know. I just got his out and got it started for him. I can tell what you may want to know.
