Default super flush system- has anyone installed one of these?

Greetings all,
Looking to install a SF400 superflush engine/manifold flusher. Has anyone installed one of these (6cyl 4.3) and how do you like it. It looks to be just what I was looking for as my system is raw water cooled and in ocean water. They install with a quick connect water feed and appear to install quickly thru the block plugs and thermostat hoses and utilize a high pressure reverse flow to quickly flush the system.
thanks for your replies

I've seen em...but never installed one..I have a reverse system on my boat but have never used it since I'm drydocked......



I'd say install it....buy it and since your in salt water all the time..it certainly won't hurt it...

Have you been watching Ship Shape TV? It is one of my favorites.......if though the man John G thinks we are all about 6 years old it is fun to watch.

I would imagine if you boat in salt water this is the thing to have. Spent alittle money to save alot of money.......

I think the units start around 300 bucks. If you get one let us know how easy or hard installation was and if they work.......

I might be a sucker or just a little anal but when it comes to my baby an ounce of prevention...well you know...
It's $299 plus about $15 for shipping. I ordered it and we'll see how it goes. Just seems to make sense to me as I am raw water cooled and it is sure a lot cheaper than adding an aftermarket fresh water cooling system that still has salt water in use. Only 4 block connections and a quick connect thru hull fitting plus hoses so it doesn't look that tough. I will let everyone know how it goes.
thanks

I ordered it and am just waiting for a free day to install it. Be aware of one thing. The kit only comes with two Merc drain plug adapters. If you want to hook it up using four drain plug adapters, you'll have to call and order two additional Merc "EZ" adapters.

I would be interested in your testing of it. I saw their ad, but I was skeptical. I was planning on a DIY set up where I tee into the raw water hose in the bilge with some PVC. The one thing I was planning was on having two hoses feed the water supply as a single hose just doesn't produce enough volume of water or pressure.

I think the theory of the system is to utilize the high pressure developed from the injection manifold to "pressure wash" the system out. Just using a garden hose will not give the same pressure. The complete system installed rather easily but took conciderably longer than the 1 hour advertised. I also spent a lot of time trying to get the plastic block manifold hose connectors screwed into the block. The threads just did not seem right and I was afraid of them breaking in the block. I have written them on this to see if this was a common issue. The kit came with 4 brass fittings and 2 plastic fittings along with another fitting if you require a knock sensor connection. I would have preferred to use the brass fittings but the threads were not the correct size.( I was installing on a 4.3 V6)

Once installed it is very quiet to use and very easy.


I was told by my mechanic to let the engine cool prior to flushing with this system as it does not make sence to run cold water thrue a hot engine.

After I broke the plastic fitting that came with the kit, I ordered a 1/4" NPT to 1/2" NPT adapter to screw into the block. This eliminates the need for the 1/2"-13 SAE to 1/2" NPT adapters that come with the kit.

[Hijack Warning]
We set it up on our DVR and watch it religiously. Though the show is a thinly masked 1/2 hour infomercial. It cracks us up every time he 'showcases' a new product and rolls it out on one, if not many, of his 'project boats' which are really more like his fleet of personal boats. Each time a new product is shown we laugh and say "Oh John G needs a new <Blah blah>". Genious, wish I thought of it. Count how many times he says "AAAAAAAAAND". LOL

[Back on Topic]

After seeing the Superflush system, We were thinking about it. Though i have closed cooling so the only thing I'd be saving is the heat exchanger and manifolds. The boat is wet slipped in salt water so there's not much I can do for the drive
