Well, I've talked to all my friends. Some have over 30 years of snowmobile experience and they've never seen this happen. Looks like I'm out of the group buy for the EHS controller. I was miles away from my truck and just had a bad feeling, didn't feel like riding anymore. I was near my truck and felt a horrible vibration at high speeds. I got back to my truck and took it out for one more blast. About a 150 ft. from my truck the secondary shaft ripped in two. Thank god I was went back for no apparent reason. A public works guy showed with a 4x4 gator and helped me tow it and load it in my truck!
