This is the 3rd time this ski has broken the exhaust bolts on top of the manifold. Then engine seems to be in pretty good shape and runs great. I believe there is some misalignment causing stress and the normal vibration of the engine is the catalyst. I do have the exhaust bracket bolt in place. I bought a new bushing because I was told if that bushing is bad the bolts will break. So today..... I'm pulling the exhaust and will check for stress and I will eliminate that stress but... any input would be welcome. This is so weird. I got another ski with the same engine and no issues at all.
Failure goes like this....First thing to break off is the Threaded Stud, next is the bolt to the left of it. That does tell me something of the misalignment. I might just replace the tuned pipe assembly... so the book calls it. LOL Here I go !!
Touchdowns everyone and stay safe !! Happy Easter !!
