Hi all,
I just bought a 93 luhrs with marine power 454's (closed cooling). Have had outboards my whole life and this is my first go around winterizing an inboard. Can anyone tell me the best way to fog these motors and the recommended way to get antifreeze through the block and system.
Thanks

Ayuh,... It's Closed Cooling, the block is Already Full of antifreeze....

Just Drain the raw water side of the heat exchanger, 'n the raw water side of the system....
