Hi Tom, That is a good question for Jerry. There does seen to be a number of yellow hulled M17's from the 1976 early era. I have seen several in Minnesota. Sailboats Inc. was a dealer of the Montgomery line here back then, and sold many. Mine is a 1976 hull #92, with 3 gudgeons for the rudder. It is a soft, faded looking yellow. The later yellow models seem a much brighter yellow, almost an OSHA bright. Jerry must have really been cranking out boats then, Larry's1976 M17 (which was at Havasu last year) is hull #200. Mine could benefit from some gelcoat polishing, but, I'd rather be on the water with her. I'll try to attach a pic. It was taken in the Apostle Is. on Superior last July. Later gang.
