Ok i'm still having a problem with my sled i'v replaced the head, head gasket, cylinder, and base gasket and i'm still getting water in the pto cylinder runs fine cold drops a cylinder whe it warms up




you are leaking in the case somewhere on that cylinder. Everything else was good. Do a leak down test on it. Maxdlx
Wild guess here. It may be an issue with the carb heater circuit leaking into the carb on that cylinder. Just another potential source of coolant into crankcase you can eliminate quickly by removing line to carbs. (assume the valve is BO don't just put valve in off position).

Did you use yamaha gaskets? I had a problem with after market gaskets it the past.
