Hi S- that is going to be tough to find out. I was told that Genmar "dumpstered" all the data when they bought Aquasport. Hell, we sent the "new" Aquasport customer service at Genmar a CD (JimCT did anyway) of all the literature we have so they would at least have something to refer to. Unless one of the members that were dealers fills us in with some general idea, we many never know.
