Agreed. I was so pleased that the heater had AF and not raw water. I wish they would convert everything to AF and have a bigger heat exchanger and the only part that saw raw water besides the exchanger was the exhaust. I am not sure why they still prefer water for the transmission. Perhaps the EPA/Coast Guard require water in the transmission to decrease the risk of AF contamination of the environment due to coolant leakage from the cooled prop shaft thru-hull.
