It sounds like it may be about a 1952 or 1953 model. Are you sure it was converted over? They made some of the Chris Crafts that way back then. Does it have most of the pump inside of the boat and a kind of funny plate on the back that controls steering and reverse? I restored one similar to that for a guy several years ago. Value? Wouldn't have a clue, probably just what it's worth to you would be my guess. Can you post some pictures of it, or email them to doblander@hi-techperformance.com
