Hey Guys,
Thanks all of you for your input and ideas on the manufacture of my Son's boat. We have found it to be a McKenzie approx 1959, maybe a Cherokee model, but not sure at this point. Anyway I stumbled across a picture of a McKenzie Cherokee and noticed the same lines, seat braces, steering wheel and even the same stringers (if you will...aluminum floor braces running rear to front) I've noticed the same steering wheel now in several McKenzie boat pictures. None of the boats are exactly like his, that's why I'm not sure it's a Cherokee model.
It would be great if any of you Guys out there that have Aluminum McKenzie runabouts could share your pictures. I'll start by uploading some of his now being used and playing in the water. Thanks again for all the help!
Casey
