Unfortunately I discovered yesterday the AC system is a push, not a pull. Putting the hose in a bucket of antifreeze did nothing.

I did research last night and discovered various ways to winterize the AC. SeaFlush looks interesting.

The one I like the best is to use a drill with a pump attachment and push water thru, in reverse, from the thru hull exit and let it works it's way back through the system, to the seacock, and then out the bottom thru hull.

What do others do? This was never an issue before since I kept my boat in the water and kept a cabin heater in the cabin and an engine heater in the engine compartment. Now my boat goes into a boatel for the winter.


Thanks,

I hook up a container of pink and let it pull thru. Turn on both A/C units and it sucks it thru.
I know some pump from outside, but if you have multiple A/C units that could favor one and not the other.

CurrentSea, beautiful boat, reminds me of my 2001 3780.

I have one AC, it's in the aft cabin. Pump and seacock thru hull are in the engine compartment. I tried disconnecting the hose at thru thru hull, and inserting the hose into a bucket of antifreeze. Nothing. I tried pouring antifrezze directly into the hose, nothing. There was a mechanic wintering the boat next to mine, he said the AC is a push, not as pull, that I will need to push water thru with a pump or gravity feed water in.

Most AC pumps are flooded pumps and have to be install below the water line to work they will not suck water or antifreeze unless it is poured into them.

I pull the exit hose and pump antifreeze back thru the system, I use a hand pump with the AC off.

I use a plastic 55 gallon hand drum pump. I put a plastic barb hose reducer that fits into the thru hull outlet with a little Teflon tape on it and a hose clamp on the plastic hose end. Just put the pickup into the bottle hand pump away thru the outlet hole. Make sure the strainer is clean before other wise it pushes the crap back out the hose and clogs it. Definitely easier if some helps you hold the reducer into thru hull outlet

Sounds like going from the hull exist reverse back thru to the thru hull entrance is the way to go. I ordered a pump for my drill, I'll give that a try.

Gravity feed works just fine.
Just close seacock and let it fill up, then turn it on and it sucks just fine.
I prefer not to pull hoses if I don't have to!

Gravity feed how, without pulling hoses? I tried flooding the strainer but that did not work either.

I pump it in thru the exit until I have pink come out the pink up. I have two units but only one pump I pump it in both outputs take about 1 gallon and about 1 minute per hole. quick easy and cheap!

We had a pump that serviced two compressors. So I disconnected the outlets from the pump and blew air through each compressor. Then I loosened the wing nuts on the pump housing to let the water out and that was it.

Mine sucks it.
Never had a boat that didn't.
It will lose prime if air gets in but of gravity fedit will restart

My experience has been the only systems that needed AF were the engines, the waste systems (toilets and pumps), sink drains and the washer/dryer. I blew out all of the fresh water input, AC lines, and the ice maker.

I too blow out my water lines lines but the ac is just so easy to pump AF thru. I tried one year to bow out the AC and I guess I didn't get all the water out of the pump and popped a freeze out plug I was able to replace with a screw in the Spring but I never tried that again.
I hate the taste and smell of AF in the water system so I blow it out and one good flush in the Spring and I'm good to go.

I also winterize with an air compressor, a/c and water system. It's quick and never had a problem.

I have "NEVER" used any type of AF for my 2 ACs on my 37C. Compressed air is all I ever used since 1993. Separate the pump ~ 1/2" to allow water to escape. It'll be a little funky. I used to put a plastic bag over pump to catch the gunk.
BTW; the compressed air was shot into the 2 AC discharge outlets in hull.

I use the Sea Flush system to winterize my boat. The AC won't pull the AF out of the bucket so for that system I just open the sea strainer and insert the Sea Flush Funnel and pour the AF with the AC system running. Works great.

Greg, you did it the easiest way if you back flushed thru the hull discharge site. Nothing has to be opened or disconnected and if you are on the hard, leave the seacock open and it will displace the water from your strainer and fill it with antifreeze also. When you see pink flowing out the bottom of the boat from the water intake, you're done. My AC pump won't pull up antifreeze either so I have to do it your way when on the hard or push antifreeze thru the hose from the strainer thru the pump, thru the AC unit and out the side discharge if I'm in the water. To do that, I hook a portable 12 volt pump up to the hose from the strainer to the pump, other end of the hose in a bucket of antifreeze and push it thru. One gallon does it either way. Either way works fine. No boat I've ever had would suck up antifreeze by running the pump. I have the Seaflush system mentioned above, haven't tried it yet though.

The boat was on the hard, and I left the seacock closed while pouring antifreeze into the strainer, no go, and then pouring antifreeze directly into the hose that connects to the pump, no go.

I now have a pump I bought from Amazon that works with a drill. I plan to take my air compressor with me this Friday, blow air thru the hull discharge, and then pump some antifreeze in from the hull discharge. I'm not a fan of a little bit of water left behind, coupled with air, potentially causing rust, so I'll add the antifreeze as well.

i take the hose off the output side of the strainer and pour two gallons in through a funnel with both systems running. I take the plug out of the bottom og the strainer to drain it and open the seacock when the boat comes out of the water to drain any water in the hose.

Just did mine this past weekend.

Shoved a hose into the thru-hull output and blew it out with my compressor - I have two, so did it through both. Then I used a hand pump to pump pink through the thru-hulls until it came out the intake.

Used about a gallon of pink and took about 10 minutes

I want to be prepared when I get to the boat since I'm over an hour away. For those of you that blow air thru the hull AC discharge, what do you use? If you use an air compressor do use try to get a tight seal or do you just use an air blow gun? I was thinking shop vac or air compressor, just wondering if the seal needs to be air tight.

Same question for those that do it from the other end, at the strainer or the pump.

Glad to hear this system/product works. I watched some videos on it this weekend, seemed simple enough, I'm just too cheap to spend the $80 for it.

My generator seacock got clogged this summer; I do see value in this product for unblocking something like this as well.

You have to get a good seal or at least as good as you can. If you're going to pump antifreeze thru, I'd skip the compressed air. Just leave the seacock open so you can fill the strainer and see pink exit the bottom of the boat. One gallon will be more than enough for one unit. I bought the Seaflush system. pretty pricey for a plastic funnel and a length of corrugated plastic hose. haven't used it yet. I also think it'll be good for flushing clogged thru hulls.

I pumped from outside on my old boat that had one ac unit. This boat has two units, and although they share a pump and strainer, they have separate discharges on the side of the boat.
If I pump in each discharges individually, wouldn’t the pink go through each system back to the pick up on the bottom independently?

I've struggled with AC also...finally, I noticed if given enough patience, I can fill the strainer and it WILL suck the antifreeze.
I have 2 systems, one pump. There must be a check valve cause I can't back-fill. Tried it many times, friends tried it, etc.

But 90% of the boaters near me back-fill. Someone in our club created a 5 gallon bucket with a bilge pump and appropriate fittings...it's passed around.
This is the easiest way IMHO.

For the generator, I bought a set of barbed to hose-bib plastic fittings. For the engines, I added a permanent flush. For water, I blow it through then add a gallon of AF to the tank to get past the pump....same for macerator, shower sump, head, etc. Anywhere there is a pump I like to leave antifreeze sitting in the pump.

I'm going back to the boat tomorrow to try to winterize the AC from the thru hull discharge. This is my last day to get this done before the boat has to go into storage. I'm a little anxious I will not have the right tools with me to get it done.

I'm bringing my air compressor, a pump that attaches to a drill I just bought, garden hoses to attach to the drill pump and antifreeze. I'm bringing the air compressor in case I am not successful pumping antifreeze in.

My concern is how to get a tight seal from the garden hose (and the air compressor as well) to the thru hull discharge. For those that do this what kind of adapters, gizmos, fancy things have you come up? I'm thinking maybe a PVC pipe clamped to the end of a garden hose after cutting off the end of the hose, with the PVC hose going into the thru hull. If that is what you do what size PVC, what size garden hose, etc? I'm assuming these thru hull discharges are a standard size and I can pick something up at the hardware store.

Hope this makes sense, and thanks

Seems like you are really over complicating it and risking not getting all the water out. How many units do you have? What's the point of reverse feeding it through the output. You already have a pump. Why not just use your pump to pump two gallons through. You don't have to blow the air out first. The antifreeze will displace it. If you pour the antifreeze into the pump from a height above the pump, it will self prime and push it trhough as fast as you can pour it in. Actually one of the easiest systems to do since the system winterizes itself.

Greg,
You’re not going to get a garden hose in the discharge. Just a couple of feet of smaller diameter cheap clear tubing from either Lowe’s or Home Depot that you can shove in the discharge. Cut it in the middle and hook both ends to your pump. Drop one one in to the container of Antifreeze and shove the other end in the discharge and hold it in as tight as you can while you pump the antifreeze in. You’ll probably spill a little, I usually keep a rag in the hand that I’m holding the tube in the discharge with, The antifreeze will go through the system and come out the pickup on the bottom of the boat. I use a cheap hand pump so I usually have an assistant pump away while I hold the tube in the discharge with one hand and the jug of antifreeze with the other.
Since you have one of those little drill pumps you’ll probably have an easier time trying to do it with just two hands if you’v Got something to prop the jug of antifreeze up on. That way you can use one hand to hold the tube in the discharge and the other to trigger the drill.
The whole thing will only take a minute or so once you have everything rigged up.

Thanks, this is my plan, I will be by myself, the drill water pump I have has garden hose connections on both sides so I'm going to have a challenge connecting any other hose to it. I was thinking about buying a washing machine hose connection and cutting off one end, which should be small enough to push through the hull discharge

Or, get a fitting with a garden hose thread on one end with a barb on the other. The home improvement stores often have them in brass near the plumbing stuff and plastic near the garden hoses. Either is fine.
Find a short length of cheap clear tubing that will fit on that barb and also in to the discharge. Attach it to the barb with a clamp and you’ll have what you need.
This is really simple to do once you get what you need.

If you pour the antifreeze in from a point higher than the pump, why wouldn't it work. I did my last three boats that way and never had an issue. Is there a different setup that I'm not familiar with?

Sounds like you lost prime in your A/C unit.
Once they lose prime they hard to prime unless they are flooded.
If you can hook up a garden hose to it you can prime it.
Once primed, I would just let pink go in from tank.
I make sure I close my seacock for A/C unit before boat is hauled, this keeps it primed.
Made this mistake once and I could not prime it without a garden hose apply pressure.
The pump can't pump air!

Got it done! Used 1/2" plastic hose from Lowe's, with a plastic barb to connect in to tne drill water pump, done in 2 minutes. Thanks everyone.

Yep, pretty easy once you have the correct stuff and a plan. I open all my seacocks up once I'm hauled so any water remains drains out.

I opened mine as well.

This is new to me, last boats I left in the water year round and used boatsafe heaters in the engine compartment and caframo heaters in the cabins. Used the boats year round.

Once primed, I would just let pink go in from tank.
I make sure I close my seacock for A/C unit before boat is hauled, this keeps it primed.
Made this mistake once and I could not prime it without a garden hose apply pressure.
The pump can't pump air!




Had that problem with my old boat. It wouldn’t prime by going for a ride. I guess some boats are like that.
Simplest way to prime it that I found once back in the water was to open the seacock, take the hose off of the discharge side of the pump for a second or two until water comes out of the pump and then shove the hose back on and tighten the clamps. Turn on the AC and enjoy.
Works every time!
Pulling the hose off for that second or two allows it to vent so water runs in to the pump.

Glad it worked out! The AC is the easiest thing to winterize on a boat. Now you just have to remember where you put the plastic barb and hose when you go to do it again next year.
