Great, thanks for the info. Yes I am going to run antifreeze because you never know if you get all the water out. So it took 12 gallons? Did you run until it came out the exhaust ? Before running antifreeze do you drain the water first I assume? I’m trying to store a place that keeps heat at 55 but may not make it through the door at 8ft. Other option is a not heated option but either way I want to winterize. Just did oil yesterday...took a long time to get the oil out? One other question... is there a neutral lock on the throttle? Thank you!!
