COld start at what temp? I’ve done one at -25c and it started fine. You could tell it was a cold start though.

My 25 stumbled like an old carbed cold blooded motor. Took it in and dealer reflashed the ECM with an update from Polaris. made it
much better even at -15 -20 after sitting in the trailer for a week.
