Well, basically as I recall AMF Inc. was the manufacturer and I think they were later purchased by Genmar holdings and folded into Genmar. Perhaps someone will know the whole history and share it.
So what I'll do is I'll create a AMF category for you.
I think my uncles model was the Appollo. His was about 18' long and I think it was rated for 125 or 135. He had a 115 on it and it ran in the low 40's as I recall.
I'll zip together a AMF forum and gallery category for you.
