Winterizing Question
I am thinking of doing my Koehler Genset this year. Wouldn't all be the same where it has a heat exchanger? I would shut the raw water seacock and open the strainer, then run unit with a fresh water supply hose in the strainer. After a few moments, shut the hose, and begin to pour 2 or 3 gallons of pink stuff into the strainer, letting the genset suck it through and out the exhaust port on the side of the boat. I would hate to make a mistake and have it freeze during the winter. Am I missing anything? I know I am using a lot of pink stuff, but it is cheap compared to the not enough consequence.
Comments please?

Re: Winterizing Question
I agree, running extra pink through is cheap compared to component replacement. Just make sure your gen exhaust is really pink before shutting it down. I also fill my water separator with sea foam at the same time as the oil change so that it’s gets a really good dose during the ‘pink sucking’

Re: Winterizing Question
I have had success doing my heat/air a different way than going through the strainer. First I remove water from the strainer with a shop vacuum and close the strainer and sea cox to seal the system. Then using compressed air, I blow the system out through the thru hull fitting on the port bow of my boat. The air blows all of the water out of the system through the other one or two thru hull fittings you may have. Have a spotter tell you when there is no more water.
I then remove any water from the strainer again and open and close the sea cox. The final step is to push non-tox through the system through then same thru hull fitting with a 1/6th HP submersible pump in a bucket of non-tox. I have a spotter watch the other thru hull fittings till a constant stream of pink comes out. Done.
I use a hose from the pump and hold a fitting against the thru hull fitting for both the air and the non-tox. I find a barbed fitting of the right size with electrical tape and minimal pressure creates a good seal.
I do not do this in the water, as Viper stated, my sea cox leaks a bit and would be a problem in the spring. I can't use the strainer and the circulation pump because I can't plug my boat in to get the power I need to run the heat/air, I need 240. This system works perfect for me and is easy to get to. I also seem to use less non-tox this way. Remember to open your sea cox when you're done.
Happy winterizing, if there is such a thing.

I have had the strainer cover off and have never gotten any water back up through the sea clock, so I think mine is pretty tight.
If you wanted to make sure there was no leak....just do the regular thing with the thru hull closed and when you are done ...remove the hose from the thru hull to the strainer at the strainer end and put wooden dowel and hose clamp......can't leak now and when gets to the hard just open the thru hull and remove the dowel.....done
I do my Ac in the water....but this year will be done in the parking lot due to rushed haul out.

There is fuel drain screw at the bottom of the carb which can be loosened to drain. I found this out from a guy who services these units.
