3126 raw water drain

[Strecker25]

I’ll be winterizing our 3126’s by pulling the hose off the seacock and putting it in a large bucket with 6-7 gallons of AF then starting the engine to run it through the raw water side.

On our gas engines I always liked to drain as much water as possible before filling the system, what’s the best low place to drain the raw water from these engines? It looks like either the fitting that feeds the dripless seal or just pull the hose off the oil cooler?

I know the raw water side likely won’t completely drain but I like the reassurance of minimal dilution when running the AF thru

I have winterized (in Ontario) 6 years now. I use 10 USG of AF per engine. I have a 'watcher' yell out 'pink' as soon as it is visible on the discharge, and then like to run the engines a few more seconds, to be sure, (and all 10 USG are used up). Never had a problem.

I don't drain anything first, except on the intake side, I clean the strainers, and shop-vac any water in the strainer housing. BTW, the strainer housing is where I insert a fitting and hose to the tank of pink I have setup.

I have considered draining the mufflers first, but have been unable to find any sort of a valve fitting that I could put into the muffler drain. I would want to be able to capture any water drained from the mufflers when emptied, instead of having to clean up the bilge afterwards.

Not sure I answered your question, but treat this as another perspective from a northern neighbor.

Thanks Dave. I'm sure pushing the water out with AF is just fine, especially on these engines and the way its routed.

I'm basically going to fill them up with AF and half drain it out 2 weeks later anyways when I take the aftercoolers off to be serviced.

Your DB has mufflers? Our DA goes straight out the bottom with just relief ports to the sides
