We have seen every one of the Nytros with reverse that we have pulled apart have the broken bolt issue that was posted on here a while ago. There is an updated bolt available. We have them in stock. Yamaha is going to warranty them.
From what I have found the bolt is too long. Even the updated bolt is too long. At the factory during assembly it appears that they bottom out against the driveshaft and then break as soon as the machine goes into use. This is indicated on every one that I have seen by a sheer break. They are shiny which indicates that the two halves of the bolt have been bouncing against each other for quite some time even on low mileage sleds. We are taking 2-3 threads off the new bolt and then installing them.
Have your dealer log all warranties possible. This is the only way to get problems fixed on the assembly line.
