With the XR550, you definitely need to drain both heat exchangers and the exhaust manifolds and the vDrive and the oil cooler if you do not run antifreeze through. I typically run RV antifreeze through mine (also FS44 with XR550) and leave it. One year I only ran 6 gallons through it (vs the normal 12 gallons) and did not drain afterwards. Had to replace both heat exchangers and both exhaust manifold elbows. Will not make that mistake again. 

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!!

Yes I am wondering the same thing. I have a Enzo FS44 with the XR550 in it. I’m in the mountains and need to winterize for a very cold winter where we are. Is it necessary to run antifreeze through the motor when my engine already has it? Or should I just empty the things the manual says and blow out? Also what about ramp fill? Thanks!
