I just ran -100˚ F antifreeze through the raw water side of the engines. These engines also have the pressurized drain system, but I did not drain it (raw water side).My new Mercruiser also has the pressurized single point drain although they kinda lie about that...there are still a few plugs that you have to take off near the water pump. Since my boat stays in a heated structure in Nevada now, I really don't have to worry about freezing. I don't do any fogging since I have cats.
What are you towing that with?
Also, what's the deal with some AF saying it is not intended for engine winterization? Is it alcohol? Not seeing how it would matter? I see this question getting asked a lot on FB groups, etc. Asking for a friend
There is a fogging procedure for these engines, and it is pretty similar to the old school MPI engines. So, I used my usual procedure of fogging & AF.
I am towing it with an F-150 EcoBoost, which is a little out-matched, but it is all local back road towing. I think the trailer is set-up with a bit too much tongue weight, so I'll have to measure it and adjust accordingly.
Remember all the 'fun' we had a few years ago figuring out how far to move a set of trailer axles in order to reduce the tongue weight?
