Mine is a 2007 350 MPI/Bravo 1 and this is the first time I have even seen this system and I am giving serious consideration to having a dealer do the winterization.
Any recommendations for dealers in southern NH or NorthEast MA???
Still hoping to get out again, but planning ahead.
Thanks

I always put antifreeze in mine, probably not necessary considering I fully drain the engine block and risers, plus it's stored in an insulated garage over the winter, but even so it's piece of mind knowing that if any little bit of water didn't drain out, the antifreeze will take care of it. I back fill the engine and stern drive which is very easy to do. On top of the engine right in front you'll see 4 hoses that all come together into a what I like to call a distribution area, pull all 4 hoses and back fill them until full/overflowing then put them back on clamp them and you're done. One of those goes back to the stern drive so I put antifreeze in that until it starts coming out the intake ports on the side of the drive unit. Very simple procedure and takes only about 10 minutes to do. I do use the RV stuff which is ready to pour and non-toxic. my 4.3L takes about 2.5 gallons total. If the boat is being stored outside or someplace where it's going to be cold enough to hard freeze it's worth putting antifreeze in it IMHO.
