Your video was very thorough and well done. You did a great job of explaining where things go and what they are doing. No disrespect but the install was just OK. Using way too much pipe sealant on the fittings looks sloppy. Overkill on the rightstuff for the thermostat housing. You cheaped out on the hose clamps, you should be using lined clamps your hoses will last longer and lastly watching you struggle with dry hoses on fittings was painful, a little lube goes a long way. Personally I use a little bit of permatex aviation form-a-gasket on the inside of all my rad hoses. It lubes, prevents leaks, protects the hoses and down the road should you need to repair or replace something it makes it easy to remove the hoses as it doesn't harden.
Thank you very much, I appreciate the time you took to record, edit and publish this video.
In a "halfe system" the engine block is cooled by a closed system (anti freeze). manifold and risers are cooled by sea water. In a "full system" only risers are cooled by sea water.
Just a helpful tip: When you make these videos, you really need to look at the amount of time text is staying on screen. I read particularly fast, but was unable to read most of the text in the 1-2 seconds you gave. If you can't read it out loud in the time that it's up, no one else can either.
use your on-off switch. stop-go.
I just hit "pause" and take as long as I want to read.
As I video editor I know what you mean, but I'm also a DIY marine mechanic so I'm stopping this video over and over and rewinding anyway.
The heat exchanger and thermostat housing are made of C12200 Copper
how do you winterize a closed colling system? great information and well done video!
Nice music!
beautiful video, thank you so much.
We always utilize an extended life Ethylene Glycol such as Dexcool. Never use a Propylene Glycol type of antifreeze as this type does not have the same heat transfer characteristics and therefore will not works as efficiently.
The thermostat is used with the housing that comes with the kit. When watching the video look at 6:53 time and the hose they are installing are connecting to the thermostat housing. This dual flow thermostat is inside of the housing.
Its a full system. They blocked the Manifolds @ 2:14.
Nice vid and nice kit; looks like a ton of extra hoses, pipes, tanks, housing to have issues! What is the kit (new) thermostat housing made out of?
i have a brand new SK 4821 Im installing on a 2004 mercruiser 5.0l with serpentine belt configuration identical to yours my thermostat housing only has 2 outputs...i noticed yours has 3...at 4:11 in your video it shows the 3rd hose that my system will be missing ...do you think i will have any issues? thanks in advance .....Joe
Okay, thanks!
Hi. I have mercruser 4.3 MPI 2007 year can I fitted on it, and do you know where to buy. Thanks
How do you ensure continuity to water temperature sender?
How many times can you acid wash this heat exchanger before you have to buy a new one?
nevermind, just saw the end of the vid!! thanks.
Take a speed reading course prior to viewing.
use on-off switch
For mercrusier bravo lll, 350, 5.7, 2013 how much?
I tried to remove those things you show at the beginning of the video, but none of them would move. I tried until my fingers started bleeding and hurting. Is there some kind of tool that one needs to use?
Thanks!
Good
nice job, who makes that kit?? thanks, Gary.
Did you coincider waterless coolant?
What was the original song on the video?
Hola. Tienen distribución en Europa? Gracias
What kind of antifreeze do you put in it?
Are there any kits for a Sterndrive Volvo Penta 5.0L V8 225D (carb). or should i just be looking at the mercruiser 5.0L V8 ones ? i'm kind of new in these types of engines, but it seems like they are quite similar.
+Dachillo Here is a link to the available kits for Volvo Penta engines. There are much fewer options available. www.perfprotech.com/volvo-penta-marine-gm-v6-small-v8/category/1300
@mickeniotusen
what is a "half system" ?
Is this a full system or half system?
Marine Closed Cooling Systems
The unseasonably cold weather this weekend can't help but remind us it won't be long before it's time to start the dreaded process of #boat #winterization all over again. Can it be that time already, it seems like we just got the boat out for the season just a few days ago?
There is hope though. Installing a Fresh Water Cooling System while not all together eliminating winterization can certainly help reduce the number of steps required to put the boat up for winter. The other thing they help with is less mentioned but certainly worth throwing out in the same discussion because they allow you to extend your #boating season. How you ask? You don't have to drain the engine 2 months early just to play it safe at avoiding that dreaded early freeze every boater has experienced at least once.
Here are several other good Technical Articles that explain the common terminology among with suggestions.

MUY BUENO EL VIDEO LASTIMA QUE ABORDO NO SE PUEDA HACER LO MISMO
Cool! Make one Kit for the new Merc135MPI, i buy it. Dont understand that Merc itself is so stupid still cooling Engines with Saltwater, thats yust stupid!
should this be done on fresh water boat?
Hola! para que sirve ese sistema. tengo una bayliner 1995 mercruiser 4.3
yo tambien tengo una bayliner 1995. ayer me regalaron este aparato y lo voy a instalar. es enfriador.
Es lo mismo que un radiador de carro. se utilisa antifreeze y mantiene el agua fria.
How much this kit cost
I dont get why you couldnt just modify a typical Chevy cooling system for a 4.3 to work for a mercruiser or OMC 4.3.
I cant read the text before it disappear.. why not tell what you are doing?
how much does this system cost? Mercruiser 454
+Rob Mehta This particular system of for a small V8 engine. What year and model of Mercruiser 454 do you have? Here's a link to the available 454 systems www.perfprotech.com/mercruiser-gm-74l82l-v8-fresh-water-cooling-system/category/1292
+Performance Product Technologies Thank You! I'll have a look. 95 454's on mine, non-efi
No thermostat?
Holy shit that is way too much sealer no reason to use it on the paper gasket
I only dislike this video because of the music. I actually like the song, but come on! I don't want to hear it 3 times during your video.
Great product otherwise.
Annoying freaking music,,too many hoses,, too messy looking. Ugly and unreliable motor,,WOW cool water option,,just to rip off more people,,like a GPS option in a car,,just to rip you off, that's all that is.
Bruce I'm sorry you are frustrated. Closed cooling has nothing to do with a "WOW cool water" effect as you said. As a matter of fact the operating temperature stays exactly the same as it does with the open/raw water cooling system. It has to do with protecting the motor from corrosion which is the #1 cause of failure to marine engines. We have many basic articles on our website that explain the technical aspects of Closed Cooling among other marine industry related topics if you would be interested in gathering a basic understanding of these topics.
Bruce Truong dumbass..that's all
