Mine made it 10.7 hours before it lost an oil line to the crank. I’m waiting on an update from the dealer on how Polaris would like to proceed. There are lots of rumors flying around about poor cylinder plating (which I don’t buy) and further rumors about the PTO bearing being mis placed on some select sleds, blocking oil flow and popping lines off the PTO crank bearing housing. The sled was a ripper until my oil line came off. I’m hoping for a new crate motor. Fingers crossed that this doesn’t affect too many new 850 owners this early season.
