Winterizing without Sea Strainers
So I have been scratching my head about winterizing for a week now and have to get on it because my pull out date is fast approaching.
The 1988 Santego has closed cooling, so the system works like this (I think The raw water comes in and goes straight to the Walter V-Drive and from there it goes to the transmission cooler on the way to the water circulator, where it goes through the engine heat exchangers and then out the exhaust.
I have read through the Walter info and the engine manual and there are suggestions to pull and drain everything. I was thinking rather than go through all that, can I not plumb in two Perko Flush Pro gizmo's into either raw water intake and then use the engine to draw antifreeze through everything and just leave it?
What do you guys think?

Re: Winterizing without Sea Strainers
It would be nice to be able to run the engines on shore without resorting to the plunger thing you describe (which I believe is a Fake-A-Lake - genius product name! ) but the likelihood of ever needing to run the engines on land is remote.
I'm guessing the sea strainers will have to be installed at the water line? Otherwise one would never be able to clean them while the boat was afloat? How does one go about determining the water level while installing a strainer in the water?

Re: Winterizing without Sea Strainers
My boat has strainers on both the a/c as well as the genset systems. I decided to have bronze strainers installed for the main engines.
That being said, for your application, perhaps you can take the raw water intake hoses off the thru hull and put them into a 5 gal bucket. With engine running flush fresh water (5-10 gals) through the system and then dump a bunch of antifreeze into the buckets. Have someone aft looking for pink.
As far as the Sea Flush and the a/c... I just utilized for the first time and am very happy. The technique also pushed plenty of gunk out of the cooling system. I would suggest you look at the online video. You did not waste money on the sea flush because it does a good job on a/c. Good luck.

Re: Winterizing without Sea Strainers
Can't stress enough that the more water you get out of the system prior to running the antifreeze the better you'll sleep all winter not having to wonder whether you diluted the antifreeze enough to cause a major failure when temps take a dive. If you have mufflers, drain them too.vineyardgray wrote:Source of the post.... I have read through the Walter info and the engine manual and there are suggestions to pull and drain everything.

Strainers should be mounted below the water line.

Re: Winterizing without Sea Strainers
For then engines. Drain the engine of water with engine drain plugs. Then simply remove the coolent hoses on both sides of the thermostat and fill the block with antifreeze. Make sure to drain your muffler also.

Re: Winterizing without Sea Strainers
I know a few boaters that use the Sea Flush system to do their ac so it does work. Ac pumps don't have any ability to to suck fluid, they simply move fluid but their design gives them the ability to run all day and run that way dry if something happens. As long as the liquid is introduced above the pump, the pump will move it through the system. Sometimes it takes a while and may take some priming but I've seen it done. Some guys will also use a vacuum on one of the discharge ports of the hull to get it started.
