VP Neutra-Salt Engine Flush System?

212rowboat

Does anyone have any experience with this thing?

From what I understand, a quart jug hangs out next to the engine and the raw water intake that intercepts the raw water coming in, and injects it with this 'neutra-salt' stuff when the operator hits a button (and holds it for 45 seconds) at the helm... the idea being the raw water ingested is treated, neutralizing the salt via chemical reaction, and adhering to hard parts (similar to some coolants which 'skin' hard parts) all in effort to protect against corrosion from salt.

it's marketed by VP, and I have read where people swear by it, but haven't read any hard data on it (comparisons). 

I've also recently read where simple fresh water flushing for ten minutes on warm engines is just as good as anything... that the damage from corrosion is when components are allowed to simply sit with saltwater in them... both sides make sense... 

I'm in the market for a full fresh water cooling kit- engine and manifolds- with raw only passing through the heat exchange (cylinder mounting across front of engine) and out the risers (via exhaust)... the risers are all the replacing that needs to happen every five years or so- it seems the exchanges hold up well (must be aluminum?).... 

I'm wondering if this injection system thingy is worth anything.... it's said you can get 12-15 flushes out of a jug.  Snake oil?

Hmmmm, I dont remember seeing the titanic all dissolved from salt.

the titanic lack's o2... o2 is needed/required for metal to rust.

If no O2 then no fish

My boat had Neutra Salt installed as a factory option. I have never used it. I prefer to hook up a hose to the fresh water port (blue cap) and flush that way after each time I run the engine. From time to time I add some Salt Away using a hose dispenser.

Chill Drew. I thought fresh water was just as corrosive. Now, when I bought my boat it was 10 years old and never flushed and it was in brackish water. Now when the boat is on the lift most of the water drains out of my cooling system. (no water in block and no risers) Should I start flushing now? I use that stuff all the time when I wash the boat, love it.

I looked in to this when I was buying my 342 as a boat in NJ that I liked had this system. Broker said that the NS removed more salt and left lasting protection and was much more effective than fresh water. But, I looked in to the solution and thought it was kinda expensive for what it was. Ended up buying a local boat but that was my experience.
