Marek I live in what some would call up north and it can get pretty darn cold here in Jan/ Feb and as I said I use 4 liters of 50/50 mix to winterize my engine heat exchanger system. The engine block itself always has 50/50 in it and this year I drained and renewed the coolant for the first time in 10 years. The heat exchanger system does not have a large volume and after a thorough fresh water flush you can run the engine dry long enough to clear some residual water without damage to anything...then submerge the hose in the 50/50 mix and let her go until you see the antifreeze color in the exhaust discharge and hold that for a few seconds...10 years with this boat, same procedure, never a problem and my water pump impellor just finished year 5, I think...maybe I'll change it next spring just to give myself an extra project...I always carry spares...I have the Sherwood pump and aside from difficulty in accessing the screws (nuts) no problems with it yet.
