Simple winterization process / draining 4.3gl

You know as long as that hose is full of water and your muffs are on tightly and you turn on the water before starting the engine it should be fine, I like to add the dawn because the impeller has been sitting dry all winter.

Thank you

Alright, so two more questions…I still have the outdrive off (didn’t get to trying to repair this Winter) and I attached the hose but forgot to put towels in the bellows before turning the water on. Some water got in the bellows and may have gone in the hole …is that a big deal or will it dry out if it did? I used a flashlight but couldn’t see if any got in there.



Second question, what am I looking for when running the engine to make sure nothing cracked over the winter. Just make sure temp doesn’t get too hot and look for leaks ?

a little spray of water in the shaft hole is not an issue

you want to run the motor up to temperature at an idle with the hose on full blast

It may have been more than a little spray cause quite a bit got in the bellows before I turned the hose off…my litte contraption sprays upwards. is rust not a concern because it will dry out ?

Thanks, figured I was probably overthinking it.

Look at lower section of exhaust manifolds and engine block for cracks & rust stains and for water in the engine oil. Since I fill mine with PG AF I always verify freeze protection with a refractometer.

I mix my own....cheaper than -100 (-55 freeze protection) 50/50 mix gives you freeze protection down to -26, but can increase it to suit your climate.
Does it help reduce corrosion? 1988 block and intake are original, used in salt water close to 25 years now, 6 month season, moored in the salt, no flush till the end of season. Heads were replaced but due to overheat damage.
I see this as the same as spraying your trailer leaf springs and anything else you don't want to corrode with lanolin based corrosion sprays....they really do slow down the corrosion on previously rusted parts and prevent it on non rusted steel.
