Ski-doo had some big time drivers early on led by Steve Ave and Duane Eck. I had a friend who raced with them and said Duane Fransden might have been the toughest to beat back then. Ave's record of course is incredible and Eck ran so much out west I never got to see him. Duhamel was very special and was so good for racing. I think everyone was at their best when on the track with Yvon. You had to be or you were going to lose.
I am glad he got to be part of our vintage hobby in recent years and I am sure he enjoyed it as much as we did.
