I was hoping someone could help me out. I have a Crownline 215 CCR with a bravo one outdrive and 5.7 Mercruiser engine. I just got this boat and it is still winterized. I went out with my muffs expecting to put them on the outdrive and flush the antifreeze out but there is no where to connect them. There isnt the trypically holes on the outdrive for water intake. I cant seem to figure out where the water gets taken in to act as a coolant. Any ideas???
