Bravo III Sterndrive
Does anyone have any thoughts on draining the block, manifolds and hoses after winterizing? The Mercruiser manual for my 2001 raw water cooled 5.0 EFI Bravo3 seems to suggest filling the system with propylene glycol but doesn't require it. Many popular boat sites recommend leaving the system drained because "air doesn't freeze". On the other hand marine engine antifreeze contains water which promotes corrosion. I am interested in knowing what others on this forum do.
Thanks for the help.
